KB Question

Have a 02 gt 5 speed 9 psi kb, had it about 4 months been working awsome. lately,not all the time when shifting from whatever gear say 3rd at 5800 and hit 4th hard the car will quit,smell like gas bad. it will not start till i stop the car turn it off then back on and she runs fine again. She dynoed fine with air fuel good at 418hp 430tq. any ideas will help before i take it in. maybe something simple. mass airflow sensor maybe?

Have you checked your coil on plugs? Sounds like the car isn't firing for a second and is flooding.

sounds like a tune problem to me.......

I second that. But I'm no expert.

If it were the tune it would of done it at the begining right. Tunes dont change. since im over 400hp you think maybe fuel pump or fuel filter.

You didn't list your mods, nor do you have your signature loaded. If I had to guess based upon just the descpription that you provided, I would say that you're probably running an FMU and that the FMU is sticking in the "closed" position after a WOT run.
