Custom Modifications  

Our expert guidance is available at 770-949-7191. Please call to discuss your specific needs.

The following suggestions represent only the tip of the iceberg where custom modifications are concerned. We have supercharged cars or turbocharged trucks of many makes and models. We have put a 4.6 L Mustang motor and transmission in a ’79 Ford pick-up. We have re-engineered the transmission cooling system on an F-550. We created a propane system for diesel trucks that will decrease fuel costs. We can custom tune your vehicle, stock or modified: a basic street tune all the way up to a tune with multiple vehicle modifications to anywhere in between starts at $500. If you know what you want your vehicle to do and it’s within the laws of physics, we can make it happen.

The three most important pieces of information that you need to know while driving your truck are boost pressure; exhaust gas temperature (EGT) and transmission temperature. A boost gauge measures the amount of load on the turbo; the EGT gauge measures the amount of load on the engine and the transmission gauge measures the temperature of the transmission fluid. You know how well your turbo is performing when you know your boost pressure; you know the temperature of the exhaust going into the turbo when you have an EGT gauge and you know before you (oops!) exceed the maximum transmission temperature when you have a transmission temperature gauge. We can build and ship you a pod with these or any combination of gauges, painted to match your interior and all you have to do is follow our point-by-point instructions to install. Some gauge manufacturers offer gauge kits while our custom-made gauge pod comes to you completely assembled with Autometer gauges and ready to install.
