Took the ride into MTI Racing in Atlanta a few weeks back to install a BP cold air intake and get a tune. Dyno numbers went up from 526/507 to 557/537, but the car was surging. After determining it was the box, we switched to an LPE Intake, snout and pulley and re-tuned. What a difference, numbers rocketed to 603/599 with a gain in torque of nearly 90 ft lbs at 3100 RPM's. The upgrade also resulted in a new more distinct supercharger sound which is awesome.

Wow, awesome figures. You're gonna have to get a vid uploaded on here to see and hear that new distinct whine.:thumbsup:

When I got my car back from LPE I noticed the same whine. I love it. It sounds like a mini dragster when your in the car. I added a few more goodies to get 659/633 on the dyno at LPE

LPE does a great professional job. I've had the car back now for about 10 months and she runs perfectly.

Any updates on performance and or problems? I am thinking about the LPE snout and pulley swap. How many miles have you driven with the upgrades? I have a 2010 bought last september and have 13K miles on the car so driveability is very important. Any info you guys share would be greatly appreciated.:cheers:

Have had zero issues with my LPE upgrade, car runs great.RFelton1 went a step further with his upgrades, but no complaints on this end. Car is significantly quicker than stock which I thought was sick fast. The snout, pulley, tune etc was less than 3K, my vette brother went a little further so I assume it cost a few more bucks as well.
