Pop on over to Ft johnson some time and we can do some logs and see where your at. I wonder what the timing is at from C2 out of the box. Water/meth would be nice if the timing was agressive, 22-24deg. but if you keep the timing lower you can run higher boost to make the extra power. Depends on what your setup likes more. Some cars/turbo like more timing and lower boost, or vise-versa. personally I run less timing and higerboost that way if you A: get bad gas you dont risk deto, or B: if you run out of meth you dont risk deto. But C: to high of boost can raise the chance of detonation too, so it all depends.
