I just aquired a 88 chevy c1500 fullsize pickup that has the tbi 305 in it and am wanting a little more power from it. How difficult would it be ti tune the tbi sys after installing a comp 268h (read thats a pretty popular cam) using a performer rpm 4 barrel intake, a machined, bored and ported tbi with adj fpr and 350 injectors? The truck has a 7727 ecm. I read that the engine is only rated at like 175hp and I'd like to see it around 225 at least. I already have plans and parts for a complete high flow exhaust system, underdrive pulleys and a custom cold air intake. I want to try to keep everything nice and simple and still be decient on mpg's. The truck currently has 3.42's behind a 700r4 tranny so the rpms are a little above 2,000 for about half of my daily commute.

Thanks,

 

You should probably repost this in the PROM chip section. Though you can probably get some help from us in the TBI forum, you could get alot more from those chip tuning guys in the PROM section.
