The valve springs didn't fix it? Damm! did you drive it on the street yet? How does it run on the street? does it fall on it's face at 4700 RPM or does it keep pulling? Can you post the dyno sheet? What did Geoff say? Call me tomorrow Dallas. Anyone else have any ideas? If it's a fuel issue the tuner should know. When i talked to him he said the A/F ratio was good through the pull.
the new valvesprings are on,havent drove it yet still over there.....think im gonna go pick it up tomorrow and then take it to get a custom y pipe and take the cats off and the cutout.........and hopefully thats the problem...
well finally drove the car today and felt good pulled hard all the way through 4500+.....sounded pretty sweeeettt...but still on the dyno it hit a plateau around 45000.....confused????

Glad to hear it pulls good Dallas. Dyno # Are cool and all but we'll find out when we take it to the track. lol Did it pull good all the way to your shift point? I got the dyno sheet you sent it looked like valve float. When you get the cats off it will wake it up a lot too.
its not valve float and its not a fuel issue...it has to be the dyno. no matter what dyno you go to its gonna do the same and show the same peak at the same rpm...its the same as my car i have dual valvesprings and more than enough fuel but drops like a fly after 4700rpm but when i get out on the street it doesnt let up until i shift...
