Well I am going to datalog my STFT and see where they are at. I have a feeling that my car is running a bit rich, given that you guys are getting better mileage than I am. It’s winter here, so I have been babying the car and staying out of boost.
I wish I had my wideband fully functional right now. I’ll get to that next week when I have time off of work!

Hey Jason, just my personal experience talking now but I've found that my mileage (before the blower) varied ALOT between tuners. I'm going to make this statement and before any 'Bamaheads jump in here, let me clarify that I am NOT bashing Doug at Bamachips. BUT, when I ran his tune (about 2 years ago now) his tune got much worse mileage compared to the tune from Brenspeed. Both of these were canned tunes and they were both around 13/1 air-fuel on the same dyno, same day. They both had roughly the same power too if I recall correctly. Just FYI, that's all.

I think I might pay Brent a visit in the spring. I will probably purchase some CMCV delete plates and have them install them too.
My current tune works very well and I am very happy with it (besides the MPG), but I'd like to compare different tunes.

Myself, I am running the following performance stuff:
Vortech S-trim at 11psi----3.48" pulley
Steeda CMDPs
FRPP 39lb injectors, Dual GT 500 fuelpumps, dual driver modules
Autolite HT0 plugs gapped at .032"
Comp Cams stage III with matching springs
Stock Bottom End
FRPP shorty headers, Mac O/R H pipe, Mac mufflers
XCAL II tuner(dyno tuned at pro dyno in charlotte, NC)
SPEC III clutch--Alum flywheel
Spydershaft
FRPP 4.10s, Mosier axles
Thats the highlights, as I'm sure i am forgetting some things as well.
Along with suspension, wheels/tires, and other stuff.
Looking at going meth injected this spring at 12-13psi(mayby).
Also plan on adding GT500 or V10 throttle body and switching to long tubes sometime soon(currently in the works).
