If so, with or without a tune ? How does it behave ? Thanks |

There is still a need for this thread...
I have read those other threads, and I want to pull the trigger on this mod. I found a dealer that will install it without voiding the warranty. (but it's $2500 to do so...:yikes:). However.... I am going to try to talk him down a little. With all the threads out there about hot cams, I have yet to hear a video of a 2010 Camaro LS3 with a GM Hotcam..... or...... see an actual rear wheel dyno curve. Robin Lawrence (from GM I think) seems to be the most knowledgable, as he has installed one in a stand alone LS3 and provided an engine dyno comparison of a bunch of cams.... http://www.gmhightechperformance.com...son/index.html... no videos though. http://image.gmhightechperformance.c...ngine_camshaft... I need to teach these guys how to make legible data charts in excel :) So this thread should be for........... Finding the 2010 Camaro Hotcam Video..... if one exists. If we wait a few weeks and still no video or dyno charts... I may have to be the first one to pull the trigger. I want more low end HP, low end torque, noticable lope (even with stock exhaust), and my factory warranty. Drivability is not a big issue to me... as long as I dont stall at the redlights. I am torn b/w 2 mod plans that will cost about $2500 each... 1) LT's, HF cats, cutouts (or catback) and tune 2) GM hotcam (w/ factory tune) + muffler and resonator delete |

He (the service manager) said it would be 2-3 full days of labor for their best engine guy (20+ yrs experience). Also, the parts list is a little longer than just the camshaft itself. There is some kind of conversion part for the LS3 and some special bolts. quote from Robin... Quote:

Thanks for the info guys.
I am with Bell here. My dealer will cover me powertrain warranty wise if I use the GM cam, weather they install, or I do. Which is fantastic of them !! However, they cant cover with a tune, as the system connects your car directly to GM when they plug it in. So a tune is out of the question. Thus the reason for starting this thread, for the unanswered questions thus far, like what kind of street manners does it have - particularly WITHOUT a tune ? Quote:

Yep, same thing. If your dealer is willing to do that, the warranty would fall on their shoulders, as GM will automatically void you (as far as I understand) once it connects to their system. You just cant hide a tune from GM. Perhaps that is part of the increased labor price they are charging ? As far as I have researched so far, the new system that these cars are the first to use connects directly to GM for diagnostics and updates. The dealer has no control to hide a tune. Even a spare pcm wont work, they are tied to the vin and compare odometer readings to the other onboard systems.
The long and short is - reflash the pcm - lose the GM powertrain warranty period. What a given dealer wishes to warranty is their choice - and thier word. Be careful !! Everything above is based on reaserching mainly on this forum, and talking to my dealer. The truth is that nobody seems to be sure about this, and I choose to err on the side of caution. Lots of people are tuning their cars though, so we'll have to see what happens when some of them get into warranty issues :popcorn::popcorn::popcorn: Quote:
