I have the following power mods installed on MY06 STi:

GST stage I shortblock (stock heads)
PE 850cc injectors
FP Green (8cm hotside)
Perrin stealth FMIC
Perrin blow-thru boost tube
P&P stock header/Injen X-pipe
SMC meth kit (70% meth, 30% water)
Cobb 3" TBE (race, no cat)
Cobb V1 AP w/GST 91 & 91+meth maps
HKS EVC @ 19psi 91, 25psi 91+meth

Note I am not listing supporting mods (cooling, braking, suspension, etc) for the sake of simplicity. I'm looking to get 25-50 more whp with minimal penalty to spool. So far, I have identified a few options:

Upgrade OG green to HTA green (????$)
Upgrade to TiAL EWG, Grimmspeed v-band DP, retune (~$1300)
Upgrade to custom divorced DP (possibly negating need for EWG)
Upgrade to Dom3.0 (not enough power here to make it worthwhile, IMO)

Custom DP would be made by a shop down in Woodland Hills just getting into the 'rex. I may be able to provide my car as a test mule and get a custom 3" TBE at little or no cost if things pan out.

With the money that I've spent on this car, I'd like to get something closer to 375-400 whp (on GST's Mustang). Any thoughts on the above options? Anything I'm blatantly overlooking? Any constructive criticism/input?

Please, let's not turn this into a FP bashing thread. My experience with FP has been overwhelmingly positive and I would like to at least consider the HTA green option.

TIA

TTT

No takers?

hmmm well if you have the funds for the new HTA green you might wanna go that route..... i havent heard much about it but i hear it spools up quicker and puts out a little more power. or you can just scratch your set up now and go rotated.

Mike @ GST claims you actually lose a little down low to gain HP up top with the HTA green. I'm not wanting to sacrifice spool, so that may not be an option.
