Sorry for trying to bring a little humor to this forum. I didn't get the memo that said I had to coddle every new noob that couldn't figure out the search feature.

 

Fairly sure it is efi. And no it's not, it has an x pipe borla exhaust, 70MM throttle body, CAI, underdrive pulleys, stage 2 clutch, 3.73 gears, and I just ordered a Bama tuner 2 days ago!

 

i dont know where youre getting the facts on how much hp a turbo or supercharger will add. 85% is at the very high end of those numbers. and 350-400 if youre talking rear wheel hp isnt as easy to make as most people think. what year engine is it/? to make 400rwhp your talking about an engine thats making in the 475 to 500 range. a small 5 to 6 pound supercharger on a 86-95 5.0 with a few bolt ons is maybe going to make 300hp to the tires with a good tune. i would honestly start with doing heads cam intake , upgraded fuel system and a tune. that will get you around 300 rwhp also and then if u have the money down the line you can go with a 6lb supercharger kit and get another 60 to 75 hp to the tires or if you think you want more go with a better supercharger kit. any other questions i would be happy to help with, but i would suggest trying to do some more research on everything

 

hahhahaha "the pedal under your food does that"

 

bama tuner??? these are not obd 2 cars, won't work if that's what you ordered, ........chip or Personal programable tuner is what are offered for obd1 foxes, got a link to what tuner you ordered??

 

hes 100 percent correct. thats why i was wondering what year car and or engine you have. kinda confused about the whole thing, u def need to research alot more
