so is this just me or what but sometimes my tac will only redline at 4500rpms then other times it redlines 6000 or 5500......... is my tac just retarded? if i bought like a p28 would i still pass smog? (io dont got vtec) but im just sick of my car lieing to me all the time... let me know what u guys know thanks guys!

 

are you sure it isnt the tack that is stopping or is the motor hitting the rev limitor while it stops at 4500 rpms... your car probably wouldnt pas smog and would run like crap with a p28 ecu

 

nono it does hit the rev limitor but sometimes on my tac it shows im at different rpms when i hit the rev limitor......so i never know how far i can take it.... because the tac always changes on me... i think my tac is retarded or something....
