Today i installed IC Greddy R-SPL and DAMD front bumper(it is amazing! but the quality of bumper is CRAP!!). After installation i can`t boost more that 15psi even when i set DUTY 45%!!! I checked all IC hoses,still don`t know what can it be???
HELP PLEASE!!

 

PICS of the DAMD bumper please! Why do you say the quality of the bumper is CRAP? Ive never seen one in person before

 

I`ll give you pics tomorow. What about boost???

 

Bigger intercooler will lower the boost. I believe a boost controller might solve that problem. I thought you meant DAMN bumper (stock) was crap.

 

He has a boost controller already.

 

HEEEEEEEEEEELP!!!
What can it be???

 

i had the same problem as well. Do you hear a loud dentrist drill whiny sound now that you drive the car? if so then one of the 12 mm bolts connecting the I/C pipe to the turbo is still loose. its most likely the one thats lines up by the oil line going to the turbo and is a b!tch to get since a socket cannot fit in the space between the turbo and oil line. I had to rock sand down the 12mm socket in order for it to spin in the small space.
