Okay so i got a 99 gt with most bolt ons, xe270ah cams and stock pi heads ported & polished. I floor it 1st and 2nd gear feel fine but 3rd and after it starts to bog out around 3500 rpms and over my car isnt tuned yet can it be that? Or not getting enough fuel? Thanks in advance

If your car isnt tuned with comp 270s and you dont stall out all the time...thats surprising.

If its good flooring it in 1st/2nd, its probably not something like a fuel filter holding you back. Could be a number of things. Do you still have the factory 19# injectors? They are right at 100% duty cycle with full bolt ons and a stage 2 cam. Look into 24# injectors.

I would start with getting a tune, then go from there.

Like he said, im really surprised you are getting past 2nd gear lol. Def. get a tune and check your fuel filter. It's a 10$ part and takes 10-15 mins to install yourself.

I just need u/d pulleys and plenum to be full bolt ons but yes i still have stock injectors
