thats a differnt thread but ok.

there is enough fuel to saftly (being the key word) 16 psi day in and day out. WIth the install of a 4 bar you can run 18 psi. THe ecu will adjust fuel both add or subtract within certain peramiters. So you are still withen the ecu's limitations. THere are some prople on vortex that have dynoed 200whp with adiode exhaust and so on.

 

its actually in this thread if you look at your post on the 1.8t lingo and what not about half way down.

 

sorry i was talking about this inanother thread and that above is a copy and paste job from the faq's in the 1.8t forum in vortex. Forgot that was even in there.

 

i forgot to mention that you use a 4.3v fora unchipped car and a 4.7v for a chipped car.

some chipped cars have a problem with the tb closing once above like 16 or 17 psi so you add a 4.7v diode you can cure that problem. Also many claim that the boost last longer to redline.

 

so say i go with APR's chip are you saying that i might have a problem with my throttle body? I see that you say some chipped cars...i was unaware of this problem

 

i have heard that some giac chips have had this problem after 17psi but not to often with others. But it is mainly used to hold boost till redline especially for k03(s) cars and will still help ko4 cars.

 

yeah i here giac's x chip is very aggressive and that APR's is a better all-around chip

 

i thinks thats what the problem is on giac's chip. I also forgot that with the chip and diode helps ruduce timing pull and are able to add more via lemminwinks.
