30FF / Underboost

One owner's reports of low boost after an intercooler install

An owner reported low boost and an engine malfunction warning after installing an intercooler. Returning to stock and attempting resets did not resolve the reported problem. A later post reported a bad vacuum accumulator, but no subsequent repair or outcome is reported in the cached posts. The owner did not report a fault code.

Reported work and attempts7 items · owner reports

What the owner tried

None of these attempts is reported to have fixed the problem. Reinstalling stock parts, clearing or resetting doesn't show what the cause was. One follow-up post describes the same install and reversion again, and one item is earlier dealer work mentioned in passing, with no date given.

Attempted an FMIC install today and the car immediately decided to hate me post install.

Installed FMIC, took the car out around the block.

Installed FMIC, took the car out around the block. No power. Boost was around 4-5 PSI, cranked up to stage 1 map 2, on 11-25 aggressive procede. Nothing....

Brought the car back onto the lift, tightened all clamps... and I mean TIGHTENED all clamps... Back around the block, still 4-5 PSI. At WOT, "ENGINE MALFUNCTION"
