Finished my cam swap and fully ported stock heads. I am sending my pcm to bryan monday but my car sputters at above 5500 rpm is that just because I need it tuned or am I going to need a fuel pump and bigger injectors?

Thanks!

Rob.

 

After you get it tuned I would put a fuel pressure gauge on it to make sure the fuel pressure is fine. The stock pump would problally be fine but it will be working it hard to keep up. And run data master on it to see what duty cycle the inj. are running.
