That seriously put me on hold there
Was told these were caused by aftermarket intakes.. Checked and saw that members with these issues had no intakes whatsoever
Canceled my tune and got an intake instead :D
Yes, a bolt on 6spd manual F80 M3
Supra is more nimble and feels a lot lighter. M3 on spirited drives was more fun because of the 3 pedals
DD'd both of them for some time and the Supra wins as a daily because of the ZF auto trans
Regrets? None :)
