s4 turbo max psi?
Ok, so theres a debate on what ther max psi you can push, ive heard 12 and 14... I know the stock intercooler wont allow much more than 12... so with a front mount and the right fuel... how much boost can it push?

First of all...at 15 PSI, the stock turbo is blowing hot *** air. second, the arc top mount is pointless because it still heatsoaks the same as the oem tmic...
better to stay at 12 psi and go with a front mount...

when i bought my car it was set up with a profec b boost controller. s5 turbo stock tmic, low boost at 8 or 9 psi high boost at 14. there was not to much of a difference and it was probably really dangerous to be at 14. I popped the motor at 17 -18 psi on a drunken highway pull(whoops).
