I am running the 93 CAI tune with raised shift points, raised rev limiter, raised speed limiter, cooler fan settings and a huge gain in power in the seat-of-my pants dyno. I am now ordering 275 or 295(if they fit) tires to keep the tires stuck to the pavement. My Goodyear F1s are now bald and dangerous. I may even check on some drag radials to radically increase straight-line performance. Enjoy.
