2004 WRX STi


Here I am looking for some advice on where to go next with power. I have a 04 STi with cobb lw crank pulley,cobb sf air intake, lightweight flywheel, invidia catless dp, cobb accessport v1 stage 2. I imagine I'm somewhere around 255whp/280wtq and I'd like to be around 285whp/320wtq. I live in Florida and the nearest tuners are in Tampa, Jacksonville and Atlanta. I use 93 octane gas and do not want a FMIC.

I was thinking that an alc/water injection system might be good because it is inexpensive, and it would let me keep my stock vf39 turbo. I read that they are safe but I am n00b to them.

Any guesstimates on how much gain I would see in power and fuel economy with a good pro tune over the cobb apv1 stg2 93 map?
