hey guys, im having a problem with my 3rd gen, from 5,000 rpm to 8,000 rpm seems to do nothing but back fire and lose alot of power when its at anything over 10psi, its still stock twins but have alot of other mods, im just wondering if its just in need of a really good tune?

List your mods and do you have a PowerFC? Kind of hard to help diagnose without the information of your vehicle.

PFC
intercooler
intake
pullys
fuel pump
act clutch
boot controller
radiator
full exhaust
full rebuild done with new rotors housings an 3mm apex seals and streetport

are you having the stock PFC map? if so, that is most likely the case. The stock map runs the FD really rich therefore a good tune is required.

yea its still the stock map, so should i get a new map or just get this one tuned?

1 more question, is this what happens after you've done the mod and have the PFC installed? If so, it most likely needed a tune.

yeah ive had all the mods done to the car for about 6 months now an since i got it back its been doing this

yep, that's what i am thinking. The car is currently running way too rich therefore it requires a tune to straighten up the MAP.

Good luck, and let us know the result once tuned.

hey i havnt gotten around to tunning it yet but i need some more help since last night if i get it up to 5000rpm it starts poring out white smoke out the exhaust an some in the engine bay, but only when i drive it if i have it sitting there an rev it theres nothing any ideas?

so this problem has just started? i would start by checking all the lines in the Rats nest i know its a bitch. but i could be as easy as a boost leak out one of the hoses... if your getting smoke under the hood. i would follow this up with a solid tune for the car.. even running the stock boost pattern i would get a retune and make sure everything is in perfect working order.
