Thanks Ron! I always judge how good I am running or tuning by what either yours or 68LAR is ET'ing. You both are what I am shooting for to be like with my car. I have a 499 lowdeck with eddys, M1, an AED950, and a small comp solid. 3k stall and full auto 727 (leave it in D) and either 3.91's or 3.55's (ET the same). I am putting 2"/3.5 collectors to replace my 1 7/8 Comps. Hoping for a 1/10th or 2 better. (3" headpipes, 2.5" Ultaflos, and 2.5" tails.)
