Thanked 2,582 Times in 2,051 PostsBoost is generally limited in lower gears to reduce wheelspin (although not sure how the ecu tells which gear its in, must go on speed and rpm)

Thanked 5,021 Times in 4,072 Postsmine did the same, i was running an MBC set at 14psi. When i fixed a couple of split pipes the boost then went upto 20.8psi, the standard ECU was still happy & no overboost so didn't bother lowering it lol Originally Posted by p0xy
