We are offering 10% off and free shipping for all Westers tuning orders that are placed through Sunday evening (2/20).

This is THE custom tuning to go with for the late model GM truck! It is made for YOUR truck so all of your modifications are taken into consideration along with your driving style. Normal driving, towing or track use isn't a problem. The program can be tailored to meet or exceed your needs!

BENEFITS:

30 day free trial, you don’t like it, we’ll either modify it, or send it back and owe nothing!
Lifetime warranty (no cost or fees)
Lifetime updates for all future mods ($45 shipping and handling fee)
Lifetime full price paid credit toward your next custom tune for your next vehicle ($45 shipping and handling fee)
No vehicle downtime! You will receive your recalibrated PCM before sending your core back. Want to upgrade this for other mods in the future? No downtime here either!

HORSEPOWER GAINS:

Customers have been seeing about 24-34hp from the 5.3 28-50hp from the 6.0 and 25-55 horsepower from the 8.1 motor. The spread depends on how aggressive the tuning is along with other modifications that are done to the vehicle. Fine tuning for other mods will sometimes make more of a different than just running those with the stock programming.

Orders can be placed online or by calling 1-877-482-9763.(1-508-636-0770 in MA). We will send you a custom programming form after you place your order. You can then fill it out and fax it back to us. There is also a section that will allow you to note what you would like to see accomplished for this upgrade. Some customers prefer all out performance while others want a mix of fuel economy and faster acceleration. Just note this on the form so the programmer will have a feel for what you are looking for. More info and the regular pricing can be seen on our website. The discount will be taken off those prices.
