Just wanted to post my dyno results after installing my boosted performance twin scroll kit and having it tuned by Seb and Greg from Specialty Z. Car has stock block, heads, manifolds & returnless fuel. Boosted Performance twin scroll kit utilizing a Precision Turbo PT6766 1.00ar. Haltech PP, external MAP, Haltech dual widebands, Treadstone 340lph pump, and 750cc injectors. I'm very happy with the results!

Could be so much better if you had a EBC to avoid those spikes of boost from 6 to 8. Also your AFR should stay in that 11 to 11.5 range and not drop so much to the 10's. They should be able to clean that up a bit more with fine tuning.
Best bang for your buck for EBC that's also a Boost/Vac Gauge and has Over Boost Protection... AEM Tru Boost.

Yeah, I second guessed myself when comparing the torque curve vs. boost. There would have been a definite torque spike with 2psi...like 30 ft-lbs if I had to guess.

This car has the Haltech dual widebands, and the reading was taken from the driver side bank sensor.

Nice torque curve!
I'm sure the wideband log on there was slightly different than what was being read on the haltech although there is a slight drop in hp at the area demonstrated with low a/f so it could be true.

Thanks for all the comments guys! The car pulls hard, and driveability is awesome! I'm really enjoying having a boosted car again. I actually have a boost solenoid for the Haltech, but we disconnected it and ran just off the wastegate springs while on the dyno because I had it plummed in wrong. Now that its boosted and tuned I just plan on enjoying it for the summer, and hopefully doing a simple engine build in the winter.
