Hey guys i need ur help. I drive a 2000 mustang gt automatic and every so often i go to hit the pedal my rpm's fly to 1500 but then slowly move from there and then i can;t hear the exhaust anymore and then it just bogs would this be a fuel delivery problem or a ****ty tune because im supercharged and intercooled and my tune is just ****? Im running 42lb injectors and a new maf but all my friends are telling me its either fuel delivery or a ****ty tune? PLz help

I have a procharger 10psi on my 03 gt and every now and then while I'm driving when I punch the gas there is nothing for like a second then it responds. It never did it stock. Its nothing I'm worried about. Do you have gauges like boost and fuel pressure.

What type of sc do you have and do you know if the fuel pump has been upgraded.

Are u running 10 PSI on a stock bottom end? if so any troubles?

Obsequious1

I've been running 10 psi intercooled on a stock bottom end for over a year now. My only trouble is trying not to break my 315/35/17's loose in 3rd gear.

well maybe there will be a pulley upgrade in the near future.

I had my car dyno tuned, to be "safe", I left it @ 380rwhp 375rwtq. I was told I had more to go but I was worried about my STOCK bottom end.

tricky stuff dude. maybe i will leave it where it is for now planing on a rebuild in the next year or so after that well we will see.

im running a paxton novi 2000 on 8lbs of boost but i think im running a stock fuel pump and also it doesn't like bog then quickly respond like a hesitation it will stay bogged untill i shift back down

im also getting the gauges afr and boost and fuel pressure soon so when those are installed that would probably be a big help
