iv got a 2000 XL, which has the same powerplant as the phazer, and im thinking of putting an AAEN pipe on it, but i have no idea how to judge the new sizes of jets to put in and if i need to do any clutchwork afterwards to get max perfomance from the pipes. i dont want to run it lean or anything or burn out my engine or clutches. i would most likely get someone else to do it for me, such as a yamacanich, or someone who was a mechanic for a racing team. any advice would be greatly appreciated!
