Heads/cam problems UPDATE :-)

Well as some of you know I was having problems running rich with any programming. Well someone off the board sent me a program that worked on their car and mine still ran like crap with 9 deg of knock and it was throwing code 33. I forget who it was that said it on my first problem post but they said replace the map and I did. Car ran real good on the program guy sent me. Trailered to exhaust shop and drove it home. He must have different gears than me because my speedo said 130 on the way home and I was really doing like 40. My tranny wouldn't shift or so it seemed either so it was an interesting ride home. I reloaded the really rich programming from pcmforless and the car run ABSOLUTELY PERFECT!!! Well, at stoplights I do have to put it in neutral because of cam surge a little but that will be fixed when the stall goes in. I would like to say that Bryan did an absolutely remarkable job of tuning this thing. I am dynotuning it Thurs. but I doubt they will have to do much because the car is running awesome. If I didn't have my swaybar removed, I would be roasting tires everywhere without even getting on it. At least with the good weight transfer I can give it half throttle. No full throttle until I run a log of the car to get duty cycles on the injectors but I'll let dyno place take care of that. I would like to thank everyone for their help. I would have never thought to even try this if it hadn't been for this board and especially Mike (EngineerMike) for having a killer deal on heads and getting the ball rolling on this project with tons of help. You're the man, and so are the rest of you guys. Take care and stay tuned for dyno results Thurs. and track results possibly Friday.
