Track day is the 10th, and I can't wait
I have to agree with you on Laguna, I think it is a much better track. Man I wish I lived close to that track. I have tracked on it three times and it is my favorite so far. I also catch the American LeMans race @ Leguna every year; It is a tradition in the family.
I figure T-hill would be a good starting point for my coupe, since I have never tracked anything with more power than a stock S54 with an ECU tune. I will be driving through your area on the morning of the 8th and sometime on the 12th (prob in the afternoon),
Good call on the mods. You will get the best gains and performance improvements out of headers and an ESS tune. The mufflers are really just for looks and sound.
