New TB/Plenum may be messing car up... Wont downshift at WOT...
Ok so i got a ProProducts 75mm tb and plenum, installed it 2 weeks ago, love it, definitely feel a difference in throttle response but theres one little issue...
Sometimes when i floor it from a roll, the car doesnt downshift. Car is also idling a bit lower than before, about 100rpms lower.
Before the TB and plenum, i ran a 9.07, afterward, best i could hit was 9.3.
Im assumin the TPS was tweaked a bit when we were transferring it over to the new TB, but i want some input and ideas here before i go and mess with it.
