Not bad... but I still have some drivability issues that I am trying to work out. It is FAST (and loud)! Pretty happy with the numbers considering that it about 90 degrees today and plenty humid. We ran the car in 540 range cold but it was running to lean to be reliable.

Previous numbers were 485 / 493 with the intake disconnected (the stock GSM intake was very restrictive).

The revised intake from GSM increased boost from 6.5 lbs to 10.5 lbs at 6000 rpm. The 80# injectors supplied with GSM's revised control module did not work and we settled on 60#.

Modifications to date:

GSM Stage-2 Supercharger
Kooks Headers
Kooks Mid-Pipes (w/o cats)
Magna-Flow 3" Exhaust
GSM ESP module
GSM O2 simulators

I-Forged 22" 3-pc wheels
Mich. PS2's 255/30 & 295/25
KW Level-2 Suspension
Cross-drilled, slotted & nickle-plated rotors with Carbo-Tech Ceramic pads
Custom JL-Audio sound system (800-watts & Dual 12's)
UNGO remote start & active alarm with pager
EZ-Stainless mesh grill

Very nice numbers.... What is your A/F set at?

I am keeping mine at 11.5 for now.....

Congrats and enjoy!

Yes it is a 6.1

How is that Q rear-end working out? I could use a little help there.

Same thing... 11-12... I would like to see what kind of numbers it will produce when it's a little cooler.

You will love the cooler temps... I am liking your torque as well. I opted to not install the LT's and my torque has suffered because of it.... 498rwt with 522rwhp... The Q LSD is fricken awesome.... I know "C" loves his.

I recommend that you "Do Not" exceed an 11.8 A/F mixture or you will have many problems down the road.... These 6.1l's love it at 11.5 and will give you a longer life on the engine. IMO..

Enjoy!

Where are you from??? Who did the instal? If you don't mind me asking.

good to hear from you, glad your car is doing well. How are those o2 sims working?

[1bad4dr]

Are you planning on doing the Quaife upgrade?

[BigC]

I love the Quaife!!!!!!!!!!!!!!!!!!

Aren’t you over in WPB, Florida FastMax1? I was thinking that I’ve read a post from you going to Moroso’s to run your beast. Sorry if I’m confusing you with another member.

BTW...awesome numbers and if you are in Florida I would love to see such a beast first hand.
