So after I installed the x-pipe
EXCEPT - now I have an odd shake (minor, but you can feel it in the shifter and passenger has noticed it) as I decelerate down through the 3200-2900 range. It there there somewhat on acceleration - but more noticeable coming back down.
Ideas? I have a stock intake. Could it be it needs more airflow now? Would have to to tell the wife 'I have no choice - folks on the board say I have to buy a blackwing to fix this'
