Rev limiter or fuel cut off?

[1BADGTP]

First I want to say HI to everyone, I am new here.

Here is my problem at WOT the 1-2 and 2-3 upshift I am hitting either the rev limiter or the fuel cut off. It does not do it every time but still I need to get this fixed. My car is a 2002 GTP with a mild cam, headers, 3 inch pulley, 3200 stall, and a v. 1.0 DHP pcm. Does anyone know what could be causing this and what I cam do to fix it.

Thanks,
Brent

you can try lowering the shift rpm or mph on those shifts or bump up the limiters slightly

I don't have HP tuners yet, it is being purchased by my friend who allready uses it on his vette. I don't know what the limiters are set at from the factory/DHP but I do want to raise my shift points to 6400. The valve train in the car is setup to run it safley.

u wont be able to access the dhp with the hp tuners. youll need your stock tune to start with.
