yeah I feel the same with my car. I cant run faster than a 13.9 now. I dont know what is going on with it. It ran a 13.7 with an untuned map back in april at honda day. Now that I am tuned i cant get near that time. its bizarre. Strangest thing is I can trap higher than 99mph.
question about your H/E combo. im not really interested in the header cuz im not sure its street legal. but i coulc buy the combo part it, and resell the header. right?
i feel dumb asking, but i had to. really just want vibrant exhaust
