    Blackbear tune..if they can do them yet. The trucks are new,dont expect alot of mods to be there. If blackbear cant do them yet get him an exhaust job.

        I recently bought a 2010 crewcab Z71 with the 6.2, I have to say I was surprised just how much faster it is than my 07 5.3 (No comparsion at all). I havent had any luck finding a programmer or chip for it so far. I always wanted just a little more out of my 07 5.3 truck but this one is fast as heck, no complaints so far.

          yeah i just drove it, blows my 5.3 out of the water. i think the 6 spd in it helps too. well damn, a tune would sure be nice. ill have to keep my eye out for them when they start making them.

          thanks guys

            There really aren't any complaints with these motors, so far they've gotten great reviews regarding their power and performance. he made a sound choice, only other engine i'd consider is the aluminum 5.3L.

              far cry from the old rattler 6.2s

                Thought I would add- I bought an ECSB 6.2l 4x4 about a month ago and had justin@blackbear tune it. Wow what a difference. I liked it before, but now it's even better. I only have a few miles on it since I flashed it last night but it made a nice difference. The only way for him to do it right now is to buy the autocal unit, but that allows you to flash it back to stock on your own if needed.

                  The heads on 'em flow like gangbusters. I've never seen a better candidate for a stroker crank, these things are MEAN with a 4" stroke in 'em! I've seen many, many stroker builds running pump gas with over 600fwhp.
                  Now all you have to do is figure out how to get your dad to safely total the truck so you can snatch that engine out if it!

                      My buddy has a 2010 with a 6,2. Lyndon at Wester's garage had his on the dyno for about 3 hours. All he could get was 1 hp. They are set up very well from the factory. I think the intake and the exhaust maybe the restriction. He's going to do those mods and the he'll be going back. Having said that, it's still a totally different truck to drive. He got rid of all torque managment and improved the shifting. I think the truck is better on fuel too.......I'll have to check with him on that.

                        PS, IIRC the truck only made like 250hp and 275 ft/lbs of torque.

                          I think you're mistaken. Even LQ4 6.0 make more than that on the dyno. Just under 300lbs/ft tq as low as 2400rpm

                            Just remember, chassis dynos are a tuning tool. They vary greatly from dyno to dyno. His dyno reads low compaired to other dynos, you can't do the 20% rule of thumb with his. It comes as a shock I know. I bet my friend it would break any more than 275 rwhp and he thought I was crazy.

                            A stock 2010 Camaro only made 264hp on his dyno. http://westersgarage.eidnet.org/2010...o%20before.jpg I don't know what the factory rated hp is on those.

                            My truck made 284 rwhp.
                            My camaro made 318rwhp

                            In other words chassis dynos aren't for bragging rights and the numbers should be taken with a gain of salt when comparing.

                              Interesting, guess I've never been around enough dynometers to know.
