When i give my car WOT, it completely cuts out around 5000 rpms, it feels like a complete loss of power, i check my boost gauge and it stops at 6psi cuz it cant get it higher, and the afr is good 11.5-12. I have been having this problem for months and changed a couple things and still nothing.

Heres my setup
D16y7 Stock compression
240cc injectors (Dont tell me to change them cuz they support 200hp)
255lph Walboro
Msd wires and external ignition coil
Iridium plugs idk what number
Ram air intake
T3/T4 turbo kit at 7psi
obd1 p28 ecu with phearable Tuned Chip

I was thinking it was fuel cut becuze i had a diferent tune that was slightly lean in higher rpms, but its doing the same exact thing with a perfect tune and a 255lph.
I thought it wasnt getting good spark for the mixture, and upgrade to the msd power tower, imroved power but didnt help my problem.
Right now im thinking it cant be fuel, its not air so its probably spark, so maybe sprak blowout?

Any help is very very appreciated

help?

1) I've never seen 240's handle 200whp. Matter of fact I was running 310cc injectors and they were at something like 83% duty cycle at 195whp on a 1.8L motor. You DEFINITELY need bigger injectors. Especially since your idiotic sig says "240hp 8psi d16".....admittedly saying you're way overworking those injectors. Get bigger injectors.

2) What's your fuel management/tuning system?

3) who tuned it?

Questions 2 and 3 are the most important........

Agreed, If you cant afford the 50 bucks for DSM 450's then a turbo car isnt for you.

Edit: Nice sig

Ok im working the problems out one at a time this bein my current one, next is bigger injectors, and the fuel mixture is perfect as i said and it is tuned by phearable as i said and logged by me, so next time dont read half and be douschebags read the whole thing and try to help instead of shitty critics.
o and its a project as in thats my goal not my current status dumbass

roachsboosted16

phearable is in FL, and you are in CA.

did he fly to you and tune your car? or did you deliver your car to him?

because what I'm deciphering from that is you're running off a BASE MAP and haven't had your **** tuned.

Please correct me if I'm wrong.

Your turbo is making full boost around 5K, the car is going really lean and cutting out. The End.

+1. those 240cc injectors are maxing out hardcore.

FAIL for trying to use 240cc injectors.

Your injectors will make 200whp, but only with 13.5:1 AFR's, NA, at very high base fuel pressure.

You're also likely having issues with the plugs too. Iridiums are good for lasting a long time and emptying your wallet, not making power. You also have to gap them down to .028 " or so or you'll also have issues with the spark 'blowing out', making your motor break up.

i just stated earlier , at the begining post that my afrs are <U>good</U> when it cuts out, good as in 11.5-12,
The chip is a basemap yes, but i datalogged it as was also said.

roachsboosted16

FAIL.

Get it tuned, get bigger injectors, and I might give you this:

like others have said, you're stock injectors are too small, you're base map is simply that, a BASE map, not a tune, its a starting point for a tune.

^ bingo

Yea, you need an actual tune, not a basemap douchecanoe. And according to your sig, can I make one saying "400whp B18c5, 4Lbs boost!" Cause even though I havent done it(and never will) I plan on doing it?

roachsboosted16

who is going to be willing to pay me back for buying the injectors when they arent the problem bcuz obviouly im going to have to do that before anyone starts to focus on what is actually wrong instead of assuming stuff, even after i said my afr is GOOD 11.5-12 when it cuts out.

you fail at life.

As said before. Replace the injectors and get a [freak]ing tune, stop running on a goddamn base map.

240cc injectors CAN NOT HANDLE that kind of power. Fact.

Remove yourself from whatever dreamworld you occupy and come back to reality where PHYSICS LAWS apply.
