75mm TB & Plenum

[xAchillesx]

Hey all,
I have a vortech blown 01 gt. I am sitting at about 380 rwhp. I was looking to hit that 400 mark. I was wondering if any of you have experience with this combo on a FI car? If so let me know what your gains were. I already have midpipe/catback so this seems like the next logical step before trying to put in cams/longtubes etc.

Cams and BBK L/T's are worth about 50-55RWHP at the wheels...N/A!!! Supercharged will be worth even more. I highly recommend those two upgrades along with a TB and plenum, and while you are at it you should get an aftermarket intake as well.
