Yesterday I finally got all my mods on the L for now. Put the bassani catback and magnaflow hi flow cats on bout a month ago. I had been waitin on my xcal2 to do the dreaded plug changed and add the 4lb lower. The plug change was rough and took bout hr and a half. Couldnt have got it done without my buds nice swivel sockets for the coil pack screws. We then got the truck up on the Lift and went to install the the 4lber. Then thing broke loose easy for most part, we had a 3/4 in drive rachet with bout a 3ft handle on it that might have helped. I had worried bout the pulley from all the threads ive read bout people havin probs gettin em off. Last was to install the xcal2 and test drive. I love the feel of the 4lb but I can already see that with me not drivin it every day that soon Ill order a 6lb ring to up it a lil more. Now to get it on a dyno and see waht it puts down and to the track once I get my drag radials mounted. A/f was sittin at 11.2-11.6 at wot just by watchin guage, havnt datalogged it yet. epper:
