hello all,
I have a 01 7.3. I am running a hypertech3 programmer on stage 3. all was fine till i install 4" turbo back exhaust. then my boost will get as high as 25 psi. I have a boost fooler installed that limits to 16psi at computer. the problem is that whenever boost goes above 21psi i feel the truck die down. If i let off the throtle a little boost drops to 19-20 it all comes back to life. the only code i get is a wastgate control code. Is something still causing the truck to de-fuel or am I running out.

thanks in advance for info.:crazy:
