hi,
I'm pretty new to the modding my supra, and have just started on my journey to 800hp! Got quite a lot of work done so far, I need to talk to the dude that fitted this, but in the meantime i wondered if anyone on here could give me some advise...
I've just had some work done to my TT supra, and they fitted a lag swich, i hadnt asked for it, but basically it seems to make the car idle at about 2100 and run very rich, it backfires like crazy at around 3200rpm when you lift off the power - can anyone tell me what exacly you would fit a lag switch for, benefits or pitfalls of this switch?!
when its switched off the car runs much smoother and quieter like normal...
