i had my car tune in april and the tunner had to set the rev limiter to 6800 so i wouldnt lean out cause my injectors are to small (525cc) and had my idle at 1100. Well now my car idle at 500rpm and the rev is up to 7500rpm is there somthing wrong with my unit or do ijust have to get it retune every 6 months????

What sort of system do you have? I suspect that J1 has been cut.

s200 with p72

I would recommend taking it back to the tuner to have them check it for you.
