This past weekend Nick Williams finished up the tune on my 2005 GTO with a 427 Warhawk and F-1C Procharger. It made 921/861. The guys at Williams Performance in Mooresville, NC did one hell of a job putting the car together. The install is clean and professional and the tune is sweet. Many thanks to Nick, Bob, and Kenny. Great job.
I just looked at your AVATAR, is that your car from idle after you let off the brake?? J/K but in all seriousness, you have the power. Just be careful.
I Have Similar Set Up Also Running 4l80e /warhawk With Et Ls7 Heads But With Vortech Supercharger . What Boost At Intake Are You Seeing With Your Pro Charger. I Made 940 Rwhp With 10 Rib Serpentine But Resently Put Gilmer Set Up Due To Belt Slip. Hope To See More Hp On Tune But Waiting On My Yank Py 3400 Converter . How Is Your Converter Coping With Hp , Why Is Stall Low, Any Reasons.
Don't forget to thank me for getting that Katech tensioner to you. LOL. Just messing around. But seriously guys I was there and it makes me want to throw up seeing this car. Makes mine look like a bone stock dyno graph.
It scared me looking at your dyno graph!! Seeing as my 340 or so hp car seems fast... yours is over 900.... Monster power your putting out there! Congrats!
Have you mapped boost, why does the power fall off so quickly? I don't think a F1C would be out of blower at that power level, and your cam is big enough...
Congrats man thats sick power be careful and engine shot??
This is all I have right now. Sorry the quality sucks.

14.5-15 according to the MAP sensor. I only have an 8 rib belt right now and I'm pretty sure it's slipping. The converter is working perfectly. I have the Vig 5 disk. I went with the 2800 for two reasons, streetability and traction issues at launch. When I get some bigger tires on her I may go to a 32-3400. What is the CFM of your Vortech? Thanks for your input. It sounds like your setup is very close to mine.

The MAP sensor is showing 14.5-15lbs at 6300 and never climbs from there. The blower is not at max speed until 7000. Procharger told me today that the belt has got to be slipping. I am going to change it and see what happens. I may go to a cog setup eventually.
