what can i expect if i get the tbody when i haven't swapped pulleys? currently have amazon intake and magnaflow x and catback. is it worth it without swapping pulleys? anyone dyno this product with stock pulleys? how will it affect a/f?
We did the testing for Doug @ Billett Flow, and a stock Cobra picked up 11-13 HP and 12 lb ft of torgue, and now any idle hang problems, that showed up on a handful of cars is cured. The TB has jewel like quality and throttle response is awesome. Joe @ Mustang Magic :lol
