I have a A4 1.8t To4e turbo ,external wastegate 35mm with a 1 bar spring , bov ,and 3" turbo back and I just installed this setup .Every since I installed this turbo i get only about 3 psi of boost at full throttle.Im thinking that i was in a limp mode. also my n75 is connected electrically only and i have mbc

 

what kind of tuning do you have for that thing? are you sure you have all the vac lines hooked up right? is the mbc working correctly? do you have a maf? if so ditch the bov. do you skip higher then 3psi or is that as high as you go. can you make more then 3psi if you are not giving it 100% throttle?

 

no tuning yet and I just went through all the vac lines there fine,the mbc is correctly working i istalled on a friends car, i have my stock maf,I got rid of the bov and installed my stock dv,I dont go any high in boost no matter if i floor it.And I notice it happens more when i reset the cel

 

you are running BT setup with stock tuning ? [&:]

Are you crazy ? Prob. car goes lean everytime car boost up, that's why it goes to limp mode or something.

If I were you, I would not even try to boost. Get a software first.

 

NO INJECTORS?
I have a friend running a t3t4 with 660cc injectors on a stock ecu. He just disconnected his mafs and let his ecu read from the map sensor. Granted his car is running pretty rich, but it is fast as hell. he can pull me about three or four cars in each gear.

 

a4intec becarefull your going to kill your car

 

Im looking for injectors but im not sure were to find 660cc ,can you tell me were your friend got them from. Also I havent found a management system to control a T3/T04E. I was going to get a GIAC chip installed but they dont have one for me now with this set up.
if anyone know where there is one please let me know.

 

Oh just keep eveyone posted ,I tested my car out and turns out i was leaking from the charge side of the turbo .So i installed tighten every thing ran pressure through the charge side and now there are no leaks. Also codes came up yesturday P0118, P1300, P1338.
I looked it up and p0118 is a bad ect sensor, P1300 was because at that time my car was on empty, and P1338 is a bad cam sensor. So im replace what needs to be replaced today and ill let keep you guys posted to let you know if it fixed it.

 

Just so you know, your engine is not going to last very long at all without proper tuning, but you can find the injectors at any of the aftermarket audi websites.....goapr.com, atpturbo.com, awetuning.com......plenty more just look. good luck
Just curious, are you still running the mafs?

 

ya my maf is still hooked up why?should I not have it hooked up?[sm=burnout.gif]
