Im having a problem with false knock. It happens mostly around 50-55 or so when it drops into second i see 20+ degrees of knock and the car just bogs and goes nowhere. I believe its false because at 45 i can drop it manualy into second with a small amount of throttle and i saw 38* of knock. Other wise the car pulls strong all the way into OD with no knock. The tranny downshifts and upshifts very hard but only seems to do it on the 3-2 downshift. I know its false, but nothing hits the frame and it has a poly motor mount on the drivers side, and new tranny mount as well. What other stuff should i look for? The motor does not move at all while brake boosting in drive or even reverse, nothing moves or seems to vibrate. Can i get a chip that would ignore knock for the first couple of seconds during a WOT run? Thanks for any ideas

A cheaper solution would be to try a tie down strap and see if it goes away
