If you don't have the correct base firmware on your laptop that is uploaded on your proefi you won't be able to connect to it. You will need to ask whoever you brought the proefi new from to email you the firmware to put in the proefi folder on your computer.

Unless he's running a stroker and minimum 10:0 compression, I don't see how .. I'm at 9:4 ish cr and a 67mm turbo and on pump 93 did 600rwhp with cams but kick azz build he has there nonetheless
Nvm. Just re read from beginning and motor is high compression and has right sized turbo so very possible but imo would be somewhat on the edge on 93 octane

709whp on 93 at 17psi, but only 887whp at 32psi on E64? Something doesn't add up. My car picked up 100whp by adding ethanol and upping the timing at the same boost level. That would get yours to 809whp at 17psi. So you only picked up 78whp with 15lbs of boost? I bet the 709whp was with E64, no 93 octane fuel.
Larry wouldn't turn the boost up in my car past 13psi with 93. He advised against it. We have similar builds (10/1 and GSC S1 cams, but I have a 6766 turbo). My car did 460whp 13psi on 93 octane and 560whp at 13psi at E72. This was with a 6766. We stopped at 900whp and 35psi. The 6870 should be putting out a lot more power. Are you sure you don't have any boost leaks?

Ok guys, official thread update!!!
Car was trailered to Sound Performance on July18th (BIG thanks to my hommie Shawn Javorsky for coming by the house with his truck and trailer and helping out).
July 19th, Larry @ SP did all the tuning on the car. Car was at SP until Friday night. Larry and the crew went over every inch of the car to make sure everything was properly setup and safe to hit the road. Wiring was fully cleaned up in the cabin area by the ECU. SP added a rolling anti-lag switch (which I still need to drill a spot and mount on the console).
SP set up on the ProEFI... 2-Step, rolling anti-lag, traction control.
Car made the following:
709 RWHP @ 17psi on E64
822 RWHP @ 28psi on E64
887 RWHP @ 32psi on E64
That entire week was brutal in Chicago, like 100% humidity and 95-100+ degrees heat.
I want to give a BIG shout out to the entire crew at Sound Performance for their amazing customer service, work, and knowledge. These are the people to go to in the Midwest area no doubt. I have 100% confidence in dropping off my car and not worrying about a thing.
We've put about 100 miles on the car so far, it's definitely worth every minute and dollar we put into it. Installed the new fender liners, new TRD strut bar (probably the last item purchased from Curt @ Elmhurst), new aluminum splash shield, lowered front 1/2". Next plan is to make a custom heatshield for the cold air intake, get alignment done, fill A/C system, and possibly in-dash navigation/music unit install.
