My buddy Bobbys freinds M3 was faster than i thought all i have to say is i lost and i cant take another loss to this car the first pull from 40k i was hitting fuel cut so we ran again and he pulled again i was on 10psi from 14 i feel so embarissed my modds are k and n intake greddy ultimate mbc 2.5'' cat back
E36 M3 pulled from 40 - 140kph

was an E36 1994 5spd.. stupid thing i need to do somthing and fast so i can beat him before it snows here man
Fuel cut at 10psi? Check for boost leaks. These cars really wake up with a downpipe that replaces the turbo elbow and a 3" exhaust...
i hit fuel cut at 13.5 too 14 psi sorry for the confusion then for the second race i dropped it down to 10 psi for the second race it still pulled on me though. i think my next modd is going to be a 4'' tubro back and an HKS FCD to bypass fuel cut then i'm hopping to walk on it.. It was an amarican M3 but i'm having trouble beliving it was stock it was quite agressive sounding to be stock
Why do they flow the same or is just not worth the money? do you have any sug. for more power out of my supra one thats maybe unforseen to me

Are U Here 2 take My Baby
That would be graet however i feel a FCD would be an asset just incase more so for peice of mind knowing i can boost more if for some reason i need too.. I'd like you 550's and lex afm though get back to me with what your wanting for them
lol you might wanna look through some of the threads and gather info before you start turning the boost up more sir. To do it safely anyway

TS is braver than me. I wouldn't go above 9-10 psi on a stock headgasket. 14 psi is just asking for trouble.
I have a 2mm HKS HG and apr head studs. so i should be ok for the boost whats all this negitivity towards the HKS FCD?? i dont understand
FCD clamps the AFM signal. This prevents fuel cut as the ECU doesn't see the frequency required out of the AFM to cause it, but the engine is taking in more air. THis will end up with a lean condition causing damage.
It was never meant to be used by itself. It was meant to be used with the full suite of HKS piggybacks as a system.

The FCD allows you to run more boost than the stock fuel system can handle. Fuel cut is your friend. So far, it has saved your engine.
Even an MHG with ARP's will not withstand detonation.
The MHG and ARP's are only part of what you need to safely run more boost.
The stock fuel system is good for around 14 psi. I say that loosely because every car is different. I was on the stock fuel system when I detonated at 15 psi and blew a head gasket.
You should also read up on the Duty Cycle of injectors. At 14psi, you're close to the danger zone. If not there already!
I would say leave it at 12 psi until you upgrade your fuel system. But hey...that's just some random guy on a forum giving advice...

so with the FCD i can prolly run open turbo as well if there is no signal coming from the afm?? I can keep an eye on my a/f ratio i have an aem wideband i though it would prolly be a good investment lol
Their is nothing wrong with using a FCD as long as your Air/fuel is tuned. For years I used the FCD to compliment my lexus AFM/RC550's and AFC. With only the LEX AFM and AFC, I could not turn the boost higher than 19psi before hitting fuel cut. With the FCD wired in, I could hit 29psi. I had a nice 511rwhp tune at 24psi with the FCD in place.
