Was that Lingenfelter up grade on your LS2 the 500 bhp and 440 torque for about $8250 or so? And did it really make a big difference? What about gas mileage difference?
Yes, that's what they call the "head and cam" package. With a few options like the Lingenfelter Cam covers, quad pipes and the rear logo mat - the total was about $9000. It did make a noticeable difference, especially in the top end. I had put about 3500mi on the car before it went to Indiana so I knew how it performed before the upgrades. My Vett friends all are impressed with the new top end rush. It hits much harder than stock on the run up to redline. At first I wasn't sure if I'd like it because it is SO much louder than stock. The exhaust just roars when you on it hard, the intake is louder and the car rumbles so loud at idle that I have to turn it off when trying to order at fast food restaurants.
The package changed the personality of the car. Less refined, more hoodlum. I love it, and could never go back to stock. Very happy with the Lingenfelter package and consider it a very good performance value.
The gas mileage seems to down about 2 mpg, averaging about 19mpg.
