Thanks Daryl. Here's where it's at to date. Got a bunch of little details to finish up & then I think I'll give it a shot of "self-educating" primer to keep the summer humidity from getting to the metal.
Yesterday we took Jeff's camaro to the dyno for a tune. After hooking it up to the laptop we found that it had indeed had a tune-up at some point so it wasn't as far off as we thought it might be. So, the H.P. gains weren't what we were hoping for. He picked up about 12-14 H.P. at the wheels so it did help some. Turns out the MAF sensor has a flat spot in it around 4,000 to 4,500. Torque & H.P. actually drop off through that range [goes pretty rich]. So, he's got another sensor on the way. Up round 5,000 is where there is a noticeable torque change for the better. I think as important as the modest H.P. gain, once the sensor is replaced it will have a more consistent torque curve. He should be able to better his 8.87 best time to date, but we will have to wait until next week to see if the tune-up and the gear change from 4:10 to 4:30 will be enough to make up nearly .4 to beat my old 8.48 from back in the day.
His quest continues
