car sputters.

[PIMking]

When Or if I launch my car it will pull hard 12 psi but no stutter. If I drive "normal" first gear and hammer down in 2nd I get I would assume boost creep and at 15psi I looses fuel and sputters. also does the same in 3rd gear. But If I run hard 1st - 3rd no creep.

any ideas?

I know im going to get new injectors and fuel pump with safc and FPR

No hard pipes? Stock Turbo?
What is your spark doing when you give... Also with the boost creep with no tuning or Injectors, it will fuel cut at that psi. Thats what the ECU can handle.

open exhaust all the way back UICP BOV MBC now is dissconnected but still getting it. It crawls up on the boost gauge(aftermarket) and about 16 psi its starts to sputter sounds kinda like a back fire. Hope that helps.

remember that at lower rpm's you build more boost. Probably when starting off 1st gear and going deeper into the gear, when you put the next gear your rpm's won't fall as low and your boost won't creep as high. Even if you had injectors, fuel pump,etc. you need to get at least a piggyback to trick your computer into thinking you are running less boost so you don't hit fuel cut.

YOu can have all the fuel in the world, but if your computer is seeing the 15lbs of boost, it'll fuel cut. However get at least a fuel pump, some intercooler pipes, and a piggyback to cure your problem, those are basic upgrades and will improve your car alot. Oh, and don't forget a FMIC, sidemounts create higher AIT's and thus your car will knock more, so be careful.

Piggy back as in? safc?

yes sir, at least.

THere are better things like emanage, and DSM LInk, or just go full standalone haha, j/k.

BUt yeah at least an s-afc, they are super user friendly and easy to learn.

I was planning on getting all 4. safc injectors, fpr, fuel pump in the next month or so.

But back to the problem Is the wastegate not opening like it should?

Should I get an exhaust manny with external wastegate?

you can try and spray some WD40 into your wastegate, and then pull it open and close it rapidly many times repeatdly and see if that helps. But boost creep in low rpm's is normal.

What turbo are you planning on going with in the future?

I was probably just going to keep the 14b and get it cleaned. Or a small 16g dont really need the lag since im awd.
