My car made so much more power cause i have a AEM ems, with the stock ecu( it was crapping on itself) It made 260 hp.... Now with the AEM, on a base map at 10 psi it made 322hp at the wheels, I did talk to Sound performance & ask about the other guys car, the other guys car his 1jz
seems to be a little low on power, there gonna check for bad compression.

I just Wish there was a Better y-pipe out there then the China man one. If i could weld i would come up with something including a DDP
There was another y-pipe (The aussie y-pipe) that had divorced WG pipes on each of the two separate DPs off the turbos. It was a lot of pipes :)

10 psi with stock twins @ 322 hp? Stock cams? I knew the stock ecu was crap but will tuning really make that much of a difference???

mine was 294@12psi (mustang dyno though - could be higher on dynojet) stock ecu/cams/no y-pipe with the stock jza70 3" dp. my guess is with the aem ems and good tuning 20hp is achievable...

The stock ECU is not 'crap' but the advantages of a standalone are significant.

Balls on. You won't make a ton of more power (unless your motor is built to hell), but you can make a much better power band. The effects of a stand alone ECU with a good tune on the motor before the turbo reaches its' comfort zone is remarkable...
