Chrome Exhaust Stacks are Invading The West!

September 28, 2007

So for quite some time, our clients on the East Coast have been ordering up a steady helping of our Grand Rock Exhaust Stacks.  Lately, we are noticing more and more orders coming from the West Coast and let us just say, it’s about time!  With as sweet as chrome exhaust stacks look and sound, we don’t know why it has taken so long for the West Coast to represent and start shooting that black smoke skyward.

So here is the question, which cut is best?  We know that with the orders that have come through Parley’s Diesel Performance, that it is pretty evenly distributed between Straight Cut, Mitre Cut, Curved, Bull Hauler and Aussie tips; but maybe we are missing something — maybe there is a preferred style of tip.

If you have an opinion about it, go ahead and leave a comment and let us know.

Aero Exhaust Diesel Performance Exhaust System

September 28, 2007

For several years now Aero Exhaust has been taking the diesel performance muffler market by storm.  The deep throaty sound, lower EGT’s and improved mileage gains that the Aero Turbine Muffler provides has driven the Aero Turbine Muffler straight to the top of the performance muffler market.  For those of you that aren’t really familiar, Aero Exhaust offers performance mufflers for both gas and diesel applications starting at 2.5″, and going all the way up to 5″ with both resonated and non resonated models. With our diesel clients, there have been several models that have been popular just depending on the application. Visit Parley’s Diesel Performance to shop for your performance muffler today.

For our clients who are into TDI Performance, the Aero Turbine 2525XL has been the most popular model by far.  Our tests on the dyno have shown that on a 2002 VW Golf TDI we were able to gain 10hp, we also noticed a considerable decrease in turbo lag and an increase in mileage while still maintaining stock noise levels in the cab.

When it comes to performance for the Big Three — Ford, Dodge, and Chevy we recently got some great news from Aero Exhaust anouncing that they are releasing full turbo back exhaust systems which would come with the Aero Turbine Muffler in line.  We actually had a chance to get our hands on one of the prototype 5″ turbo back exhaust systems for our 2005 Dodge Cummins project vehicle.  We have been really impressed with the quality of the system all around, as well as the performance gains we have seen from it.

Duramax Performance….Jr.

September 17, 2007

So we have some good news and some bad news, which would you like first? Alright, we will get the bad news out of the way first, Parley’s Diesel Performance is sad to announce that GM has sold off their Allison Transmission division. Yup, they recently sold off their commercial and military portion to the Carlyle Group and Onex Corp for 5.6 Billion Dollars. When GM was questioned as to why they were selling it off they said that it was all part of, “supporting [their] heavy investments in new products and technology.”

What kind of new products and technology might you ask?

Well that is where the good news comes in! For those of you out there who have been dreaming of a lighter duty, “hers” Duramax Diesel to match your heavier duty “His” on the driveway, you are in luck. GM has finally announced that they will be releasing a new four valve DOHC Duramax V-8 for pickups with a gross vehicle weight of less than 8,600 pounds and FOR THE HUMMER H2! This Duramax Diesel is going to be a 4.5L and will likely make more than 310hp and 520 ft-lb of torque. So for all of you Duramax Diesel Performance enthusiasts, it looks like you have yet another way to get your fix. The real question is who will be the first to step up to the plate for performance for these lighter duty Duramax Diesels. Will EFI Live be able to take the next step and let people reprogram around regen phases etc.. If you have any input let me know.

TDI Performance Review – Van Aaken Smartbox

September 13, 2007

Parley’s Diesel Performance has great news for all you TDI owners and TDI Performance connoisseurs out there! Van Aaken Technologies has just the product that you have been looking for. If you drive one of the many 1.9L Volkswagen diesels in the U.S. there is no question that you have been in need of a little extra power; sure the economy is great but why not have a little extra power while you are at it right. Van Aaken was kind enough to hook us up with one of their Smartbox TDI performance chips so that we could put it on our project vehicle to test it out. Here is what we think:

Why The Van Aaken Smartbox?

  • 10 Minute Install- We have seen some easy installs, but wow, this one is a cinch. Since we made the install video for this tdi performance module we have had customers with no previous mechanic/performance experience reporting that they were able to install their smartbox in 6 minutes. You cant beat 20+hp in 6 minutes.
  • Economy Gains- So if 40-50 MPG wasn’t enough for you how about 1-2 MPG More. In our performance tests with the Van Aaken Smartbox on the rare tank when we could keep our foot off the throttle we were able to see an increase or 1-2 MPG which some might say isn’t huge but when you have a much more enjoyable driving experience the increased diesel fuel mileage is sort of icing on the cake.
  • Quality Product- We were very impressed with the overall quality of the product. The hard resin case of the smartbox is completely weatherproof and very durable.
  • Does NOT Void Warranty- If your vehicle is still under factory warranty all you have to do is take the Van Aaken Smartbox off before going to the dealership and they wont be able to tell that it was ever there, it leaves no footprint or flags in your system to show it was ever there.

Why Not the Van Aaken Smartbox:

  • Who Knows?- It was hard for us to figure out a reason why you wouldn’t want this tdi performance chip. The main reason we could come up with is if you are one of the more “Extreme” TDI Performance Enthusiast then you might be more interested in a more customizable performance upgrade like chipping which requires removing your vehicles ECM and sending it into a shop and getting it back a couple of weeks later and will most likely void your warranty. For some people those things sound like more fun than a 10 Minute Install, but for most of our clients this is the exact product they are looking for.

Diablo Predator Tuner Review

September 12, 2007

A couple of months ago, my boss at Parley’s Diesel Performance asked me to put the Diablo Predator Programmer on my 2005 Dodge Cummins so that we could get some real world test and numbers as far as mileage gains etc.. There had been several of our clients who had purchased this diesel tuner from us and had been reporting increased diesel fuel mileage of anywhere from 1-4 MPG so we wanted to see for ourselves what it could do.

What’s Included:  Here are a couple of pictures of what you will see when you open the Diablo Predator package.  When you first open up the package you will see the Diablo Tuner, as you open it up you will see the Instruction manual as well as a promotional Ruler.

 Why The Diablo Predator?  A lot of our clients are interested in the Diablo Predator for the following reasons:

  • Economical- Compared to some of the competing diesel programmers like the Bully Dog Triple Dog  priced at $597.99 or the Superchips Flashpaq  priced at $499.99 the Diablo Predator Programmer is a deal at $399.95.
  • Great Performance Gains-  For my applications, 05 Dodge Cummins, there are three performance settings and those are 60hp Tow Setting, 100hp Performance/Economy Setting and 160hp Extreme Performance Setting.  In my opinion its great bang for the buck.
  • Increased Diesel Fuel Mileage-  Like I said earlier we had heard from out clients that they had seen gains of anywhere from 1-5MPG, with my truck I saw about the same range actually, some tanks 1MPG better and some tanks 5MPG better.  It just depended on how I drove it, of course.

Why Not the Diablo Predator?  I have really enjoyed the Diablo Predator during the time I have had it on my truck, how can you not enjoy 60-160 more horsepower right?  The main problem that I have had with the predator is:

  • No Over sized Tire Recalibration on the Cummins- If you drive a Duramax  it’s a different story but I would have liked to be able to recalibrate my speedo to get more accurate fuel mileage etc..
  • No Speed Governor Recalibration-  Who wouldn’t want to go a little faster right?

So in the end I am overall satisfied with the performance and mileage increase for the money with the Diablo Predator Tuner, if you are running oversized tires and have the money you might be better off with something like the Superchips Flashpaq.
