So I've just installed a 4" Dump - 5" Cat in preparation to be Tuned on Friday, Problem being I need to drive 6hrs to get to the tuner. Everyone says this will cause Overboost so I took it for a drive to try and activate Limp mode so I would know when it happens and what I'm dealing with rather than finding it all out in the middle of woop woop.
Boost seemed to peak at 13psi (OBDII-android device) gunning it in 2nd or 3rd but once peaked it wouldn't boost past 3psi until the engine was shut off, no codes or lights. Made all the regular noises and ran Perfectly but with the power of an n/a xr6 and without the push back into the seat.
Is this what normally happens or am I not thrashing it hard enough? Doesn't seem so bad.
Also has full exhaust, turbo side intake, stage2 PW Intercooler. Never Tuned
