Can anyone tell me if the stock boost controller will work with a T3/T4 turboż Or if I put a Manual Boost Controller if it will freak out the computer?
the stock boost controller will work with any turbo. a manual or electronic boost controller will work fine as long as the original boost solonoid is still plugged in (doesnt actualy need to do anything though.
I got one more question. Is the stock psi on 1.8turbo is 8psi.
7-9psi is the range supposedly... tho on the 1.8 i would say more likely 4-6
watch for flying sparks!!!
