Default New Dyno

Well, with all of the dyno talk of the LS3's going around.......I have numbers of my own. The car dynoed 380.75 rwhp/372.90 rwtq with the Vararam only and we know these don't produce any horsepower on the dyno. After I spent some time tuning with the PLX Wideband, I finished with 400.81 rwhp/386.61 rwtq SAE corrected with only tuning. I used the dyno at Protech on North Lamar in Austin, TX. The low end torque is vastly improved and no knock. This should be a good starting point from mods

Nice numbers for just a CAI + tune! The LS3 is pretty stout in stock form over the older LS2/LS6/etc

Are you using the PLX SM-AFR? I have HP Tuners Pro on the way and I haven't been reading very nice things about the LC1 other than it's cheap.

wow, those numbers are amazing, especially given that the LS3 is rated at 430 from the factory. great job on the tune. I wonder what you could get out of my LS2?

We could log your LS2 and see what is available Will all of those mods, a wideband tune would be benefical.
