ISO performance tuner for a 1990 l98
How come I cannot seem to find a performance tuner for my 1990 C4 l98? I can't find anything online to increase the performance in my engine..... is there not one out there? Do they not make them?

There are custom chip makers and tuners out there that can work on an OBD1 car, what mods do you have to make it worth the expense?
If you havent increased the amount of air getting into or out of the engine this would be wasted money.

This engine is not like a C7 LT1 where a aftermarket tune nets 50hp because the factory runs the tune fat. You need a cam change, head porting, headers/exhaust, etc. to even make it worth the expense. The off the shelf chips from Hypertech are junk.
