Default 05 STi, tuned by Jorge @ P&L

I had my 05 STi tuned by Jorge at P&L Motorsports this past Friday. He really is a great guy, btw. Every bit of his reputation is legitimate. I won't launch into my long drawn out story but I'll just say that he is willing to put in as much time as necessary to satisfy the customer and make the car right!

Mods:

Cobb AP V2
GP Moto short ram
Perrin style post MAF tube
HOA 3-port boost control solenoid
GP Moto EL header
Helix catted downpipe
P&L Motorsports street series catback

289awhp / 326awtq




Any thoughts on why the power drops off on the top end? Jorge speculated it could be the primaries on the header are too small, or that the cat really is just choking it that much, or even a cracked turbo. I really would have liked to have seen the car make power all the way to redline, or at least hold and not drop off like that.

The car is a blast to drive though, and numbers are just numbers. I don't get bent out of shape because person X's car or person Y's car made this amount of power and mine didn't.

I've spent quite a bit of seat time driving around with it the past few days and driveability is amazing. I'm pleased with the outcome.

I have heard good things about Jorge, one of these days I will pay him a visit to get my junk tuned

anyways I think all VFs drop off power, too small and will not hold boost to redline with stock IWG. the more they are pushed the more dramatic the drop off will be, you could probably make more power at the risk up pushing the timing much more up top, but that leaves room to pop the stock engine

Get rid of the cat and you'll peak right around 300-305. If you do not want the drop off in power up top, then you have to make a sacrifice and bump up the timing. Some like my self opt to do so, but it may not be the wisest decision.

Helix puts the cat too close to the turbo. If you want a cat put it near the end of the downpipe like the Cobb one.

I think Jorge tuned my car right after yours.....Yours did sound nice on the dyno. Mine ended up making 284whp on 91oct. Mods are Catless turboback, CAI, perrin inlet, and a grimmspeed bcs. Didnt get my torque numbers cause I guess the the thing that measures it broke and P and L is waiting for a replacement. Jorge was very informative. Car is a blast to drive.

Its a vf39, I've never seen them hold solid power to redline. I mean look how big it is lol.

Great power though for the mods!
