could be yeh, fuel pumps not coping with supply an demand of ya new power and just doesnt simply have enough puff when its at full ring, or it could be tune related, or something completely different lol

i would look at fuel issus i know a few high hp cars that on dyno its fine but on the street/track if they gun it the fuel is not being picked up right and is starving for fuel so i would assume u may need a surge tank or something

May need to go to a higher-spec injector. As well as pump/s.

thanks guys

sounds like a fuel supply issue, but the only way you are going to know if it is or not is to throw a fuel pressure gauge on it.
