Acceleration Problem with MagnaCharger
It seems that the acceleration is strong until I get to WOT and then it seems to fall off (almost like it flattens out). Other times it feels fine and pulls well, but not through all the gears. I can't really see any black on the intake like the belt's slipping, but it sure feels like it.
Any ideas?

It seems to drop off while I'm accelerating up through the rpm range. It starts off strong and then it just seems to go flat when I reach upper rpms (above 4000).
Sometimes, I'll leave off a bit on the throttle and it'll pick-up again.

I had Second Street Speed do the install and had they try to check for problems also. They did another dyno pull and it still made the same Hp (420rw).
I am running the MagnaCharger tune. Is there a problem with it?

I have the I/C Magnacharger and I can assure you you are running LEAN, not to mention a dozen other things that super chips does. My initial readings were 22% lean R bank and 18% lean L bank. With the intercooler iat's were 150-160 due to leanness. They h
ad my RWtq set at 650 which negates active handling and TQ control.
Please get a professional tune from someone who knows the Vette PCM.
If you don't know anyone e-mail me and I'll put you on to someone who knows what their doing.
