How much boost?
 

Hey, I have a 99 a4 1.8Tquattro tip. Everything is stock except an APR chip and some other usless stuff.

In what range should my boost and Vac.be? I have a boost gauge but i don't know how much i am suposed to have.

Anybody know?

its about 25-30inHG of vacuem and 15psi of boost.
thats what I think should be

Thanks

i hope you plan on running more boost than 15psi. I run 17psi and i dont even have a chip.

RE: How much boost?
 

i highly doubt your runnin 17 psi without a chip. do you have mbc or some other mod?

RE: How much boost?
 

diode for getting past the 14.7psi limit before limp and a mbc. So once again I WIN.

RE: How much boost?
 

so basically you turned up your boost and didn't change your fuel curve or timing?

RE: How much boost?
 

thats why i can only go to 17psi and not 20-22. Just waiting to replace the my blown gt28r before the bt setup goes back on. Going back to a ko3 sucks.

RE: How much boost?
 

are you still on bt programing or ko3 programing?
