Added a couple parts and a tune

Hey guys I just got back from a trip to GST and the car feels great. As some may know I had a few problem with a flash from a well known bay area company. Well since then I added a couple parts and figured it was time for a good tune since Im pretty much done on the power end of things untill I actually learn how to drive this thing.
Mods are: 3" DP, 3"TP, RS*R GT2 catback, o2 housing, greddy licp, and drop in filter(stock 9.8hotside). For me the peak numbers arent really a big deal, it matters more to me the way the car acts in real world situations with a broad power band, and most importantly that it makes the power safely unlike it did with the other companies tune.

Base numbers were:
249.3hp @6500
248.8tq @5000

New numbers
264.7hp @6750 +15.4
253.9tq @3750 +5.1

The stock graph looks like total choppy crap and was all over the place.
The power comes on way sooner then it did before before and pulls hard through redline. The a/f hold 10.7-10.8 from 3800 to redline with boost peaking right about 21psi. I brought a friend with me and getting on the freeway when we left I went through a couple gears and he says "SOB!!!! thats a big difference! It feels like you gained a $hit load more then 15hp. More like 50hp.... At least 50"

Congrats on the tune. Yeah I know how it feels to go form a mediocre tune to a badass tune, makes the badass tune that much better!
