one more question for everyone... I am looking at the LS1 hot cam, how is it on the stock PCM on a M6 car. Do you think the diablo predator can tune up the cam enough to get by????

 

I have the hotcam and Predator tuning, the only drivability problem I have is on warm start ups it will hunt for a steady idle. I have not yet drilled the TB hole. I just did a little testing today and have my tuning set to +10% spark adv. & -2% on PE. My timing is at 37 deg. at WOT and my LT trims are 0 and ST trims are slightly negative,absolutly no KR. It pulls hard

 

I did fine when I had the hotcam with hpp3 or Superchips tuner. You'll be just fine.

 

I had both cold and hot start issues before tuning it with LS1Edit. It is fine now.

BTW, I love my Hotcam...

 

My Hotcam is still untuned. It starts the first time hot or cold. If it dies off after starting (ie-I kill it as it hunts for idle), it will take a couple of times to crank over. Other than that I love it. Sounds mean through the duals.
