So, finally got my new engine together, and trans rebuilt... ready for dyno. Get the car on the rollers and tighten down straps and do a light pull, then a full throttle pull. The dyno was showing 9 psi of boost, and the pcm was showing 8 vacuum. Turns out, when my donor car's pcm was copied to my pcm, the paramaters for the map sensor were not changed. The pcm was still thinking I had a one bar map sensor. The guy at the dyno was explaining it like when I'm going up a hill, the car was thinking I was going down hill and the power enrichment wasn't kicking in. (if that's the right term) *I had info overload today. So, now... we are going to re flash the pcm to the correct parameters and firmware and hit the rollers again on friday or wednesday of next week. I looked at the display and it was 227hp and 255tq. hoping to blow those numbers out of the water by the time this is all sorted out. Today was a real bummer. Lesson of the day, go to a QUALIFIED tuner!
