G5X3 112 Cam Only Dyno Results: 434 rwhp and 405 ft-lbs I installed the G5X3-112 LSA cam into my stock headed 2002 Z06 last weekend. First of all I want to thank TwoktwoZ06, Slythetove, jmX, Quicksilver2002 and other friends for lending a hand and/or for letting me borrow their tools.
Impressions...
This car was a bitch to drive before the tune and it acted like it had a large cam (dying in traffic, surging at stoplights, etc.). After dyno tuning the car is VERY driveable (as some of you know, my dyno tune was on 7 cylinders!). It hasn't surged, bucked, or died on me since the tune and getting the #8 cylinder working again. I can hot start the car with the AC on and the RPMs will drop a little, but it jumps right back to 900 rpms and lopes hard (very nice sound). The cars shakes at idle (I like that) but at cruising speed you'd never know there's a cam in there.
Results...
The car pulls so much harder than it did before the cam and I'm thoroughly impressed right now. I dyno'd the car this morning at a local shop and it made 434 rwhp and 405 ft-lbs tq (SAE Corrected) THROUGH CATS and full exhaust. The heads have never been off the car. It looks like there's even more left by leaning it out some.
My modifications include: G5X3-112 Cam (Patriot Springs, Hardened Pushrods, Double Roller Timing Set), LG Headers WITH Random Tech 3" Cats, GHL Magnum Exhaust, Halltech Stinger Intake, Shaner S2 Throttle Body, ASP Underdrive Pulley, 160 T-stat.
Stay tuned for videos

It's called a lean spike. Pretty common actually. Justin you might want to go ahead and upgrade the fuel pump. It will keep the pressure up in the rails so that the lean spike will not occur.

Very Nice...I noticed you have nice TQ down low and you're making power at around 6400-6500. Don't have to spin to 6800. What kind of spring change interval are you looking at with that came? Also, do you drive your car daily/couple time a week? Would you be able to sit in traffic? I want a cam but am guaging my tradeoffs. Thanks

I'll move it to the dyno section for ya 
Good results! BTW, at that very same dyno I saw an MTI heads/cam car (milder cam) do 424rwhp, so its generally a dyno that doesnt overstate numbers.
