Re: 350 ecu

The computers are the same for both 305 TPI and 350 TPI. Its the chip, memcal, or PROM that is different. Is the car running bad right now? What you need is a "custom chip" either done by yourself, a local shop, or one of the internet tuners.

it runs alright but ocasionally it will feel like its boged down and idles weird at times and when the engine gets up to temp its hard to crank up
