The first step to getting higher performance out of a modern fuel-injected vehicle is to be able to access the tuning parameters inside the "brains," or the ECM. This allows tuning of the same things that were accessible in the old-days of carburetion and distributors; spark timing, fuel ratios and much more. The factory settings are not necessarily optimum! So if you want to unlock some real performance from your modern vehicle, come see us!

Paynton Performance operates out of Stetson GM, Drayton Valley, Alberta, Canada.

KEEP YOUR DURAMAX GRILLE CLEAR FOR THE SUMMERTIME! The Duramax intercooler needs to reject HUGE amounts of heat, up to 400,000 BTU/hr in summer towing conditions! Keep in mind that turbocharger outlet temperatures can get as high as 500-600 degrees Fahrenheit! Get that grille screen and winter grille insert off your trucks! It absolutely DESTROYS turbocharger efficiency, increases turbocharger drive pressure, reduces turbocharger reliability, fuel economy and overall horsepower when ANYTHING is stuck in your grille! I have seen turbocharger outlet temperatures up to 550 degrees Farenheit, YOU NEED AIRFLOW FOR THE INTERCOOLER! Effects on the 2001-2004 LB7 Dmax: Turbocharger wastegate self-limits to prevent damage as does the MAF and ECM programming. You will only loose power and economy on a 2001-2004 LB7 Dmax, primarily towing. Effects on the 2004-2005 LLY Dmax: You could hurt the turbo on this one, and there is a drastic reduction in power and economy, especially at higher altitudes. Also increases possiblility of an overheat. Effects on the 2006-current LBZ, LMM Dmax: there are safeties programmed in the ECM for this, you will loose huge fuel economy and power when towing and it will limit power, especially on hotter days.

Many updates are coming for the website. Sorry, I haven't been able to give the website much attention for the past few months, we have been busy! Our LMM diesel tuning is being received very well, have numerous customer testimonies as to how much better economy their trucks get, not to mention the additional power! The demand is such that we are having a hard timing keeping exhaust systems in stock. We have had customers come from as far as Lloydminister, SK and Slave Lake, AB to get this tuning installed. I have had phone calls from as far away as Florida, USA and Nova Scotia, Canada for LMM DPF delete tuning. I'm working on a way of getting a remote system for customers so that they do not have to send out their ECM's, but at this point the only way to get tuning done from long distances is to send your ECM here or drive your truck here.

Check out maxxTORQUE Magazine! The magazine for GM Diesels, with articles written by Joel Paynton on the Duramax.

Custom Stack-Tunes are available. Some customers wish to run an Edge Juice product or other plug-in chip, yet they still get annoying EGR trouble codes, want to eliminate their DPF or even just calibrating the Speedometer to different tire sizes. We can build a custom tune just for your application.

ATTENTION VALUED CUSTOMERS: GM RECALL #08142. If you have your ECM programmed at Stetson GM, please indicate that you have a power program that will need to be re-installed. If your ECM is programmed elsewhere for this recall, please drop by for your free update.

2007 new-style Silverado, Siera, Denali, Yukon, Escalade: GET RID OF THAT ANNOYING THROTTLE LAG!!! We now have tuning available to eliminate this issue with the 6-speed transmissions. If you have had your truck tuned already, come by for a free update.

FORD TUNING IS NOW AVAILABLE. Numerous domestic product Fords are supported from 1996-2007! (call or e-mail to see if your Ford is supported) Experience the same benefits as our tuning for GM!

2007-08 LMM Duramax: DIESEL PARTICULATE FILTER (DPF, ALSO KNOWN AS THE "AFTERBURNER") CAN BE REMOVED! Owners of these trucks may be getting annoyed with all the "Reduced Engine Power" modes that come on when something goes slightly wrong with this system. Now you can install an aftermarket exhaust that eliminates the Diesel Particulate Filter. (This is of course for off-road use only.) Customers are reporting very significant mileage gains from our latest fuel economy tune with the DPF removed. And no hassles with cold-weather operation or going to the dealer to do a regeneration!
