Well, that is the problem Les. Without the monitoring, I just don't know. I fell off with the roadster near the end of the 1/4. The coupe feels differently, as it is still pulling. So, until I can data log, I won't know for sure where I need to go. The meth might not be needed, but it is going on there, as it certainly can't hurt with a S/C'd car. Once I can log some runs, and tweak my tune. I will add that tune to the roadster. I'm only going to monitor the coupe. But, the roadster is getting all the same parts less the meth. I was just going to keep the roadster the way it was, but, what the hell, this way I will always be ready. LOL... Sometimes I carry my Glock off duty, sometimes I carry my Colt 45...both are capable....lol.... thanks again buddy
