I have a 98 GT I have dont the PI head/ intake swap, and just bolt ons after that. I put on new Upper Plenum and a Throttle Body Spacer a few weeksago. I've been noticing when I'm driving and I punch it full throttle it chugs and then gets on it. I was wondering if it could be something with the fuel pump, if i need a bigger pump with the extra HP?
I did a tune up a few weeks before the Plenum & TBS, I changed the Plugs with some NGK and put a new Fuel filter.
