TB/Plenum How Big Of A Gain W/ Blower??

[04YELLOWGT]

Ok I just bought the Paxton Air/Air Intercooler and one size smaller pully. Im going to get it retuned and was thinking about buying a TB/Plenum.

Would they throw my A/F off if I put them on after the tune, and how big of a gain would I get with them?

I was also wondering what you think my final rwhp numbers and 1/4 mile time will be after tune?

Im running 12.8x spining like a mother (Getting some MT or BFG radials too)

whats your trap speed?
your sending the paxton back? why?
upgrading your t/b & plenum is worth 15-20hp
why not get a boost pipe?
what size pulley?

Im trapping about 109 mph

Im getting it retuned not returned.

Ive already got a boost pipe

And I think the one I bought was a 3.33.

One more thing Ive got the pully orderd but was wondering if I got the right sixe what should have I got.

3.33 with the IC should get you 8+lbs of boost.
HP close to 400!
1/4mile with DR 12.3
and I'm not sure about a/f??! if anything it would be a little rich. no biggy

since, Tim tuned your car, it should be fine without a retune. with the adaptive learning turned on, the ECU will adjust the a/f under normal driving and Tim has plenty of experience with the Maf table for the LMAF for the WOT a/f ratio.

with the Maf table for the LMAF for the WOT a/f ratio.

Although I completely understood it, that sentence made me laugh.
