The R.L.T.C. is THE easiest, as simple & as quick as adjusting the volume on your radio & will not permit wheel spin at any RPM wet or dry. Alternative #2 eBoost2 Set one of the three available boost settings points to zero. Merely a matter of pressing a button a couple of times & you have an instant NA!
Just fit a ECUTalk and set the RPM and SPEED ALARM :br: BEEP BEEP BEEP and more BEEPS until he behaves himself, :rofl:
I don't know what it's called but a guy I knew had an alarm system set up on his r34 skyline, it didn't immobilise the car or anything It just prevented the motor exceeding a certin rev limit so that if your car was stolen they couldn't thrash it, sorry I don't know much else about it :-/
