ok i have the PFC and sometimes my lift is fuked up...just today as i hit lift the car jerked like it just hit the rev limiter then im like wtf....then on the same day it would go pass 6500RPM then jerked around 7200RPM like it hit the rev limiter..and sometimes during a long drive i have to downshift to pass other cars and when i hit lift the car sounds real rough and the muffler sounds like its growling...anyone experience this? i have a 00 GTS and sometimes i hate it

could be broken lift bolts - if you get a 1693 with it then I would say low oil / sludge on the VVTL filter, but with no code probably lift bolts.

no the PFC will not give you a CEL...replace the PFC with your stock ECU and see if you throw a code...but sometimes broken lift bolts dont throw codes. only way to be sure is check...pull the valve cover and check...

Doh - with a Power FC its a whole different ballgame. Driveability issues are easier to address on the stock ECU - put the stock computer back on and let us know.

I guess with a pfc, if you have a wideband hooked up with the commander interface, you have all the important facts in front you anyway, so YOU can decide if there is a specific issue or not...i think

Hi!

I don't know if this is the case but 7200rpm is the rev limit when the car is cold and lift is not engaged.
