Ok, I admit ignorance to the tuning options available for my 05 LS2 MN6. Is the Diablo predator the only option or can it be tuned with an HP tuner? I continually read posts referencing "with a good tune..."
I currently only have the VARARAM intake, throttle body spacer, and an SLP underdrive pulley, and am considering exhaust options now.
There is tuning and then, there is great tuning. Handhelds will not give the flexibility to tune that car that will gain all of its potential. HP Tuners is a great choice but, there will be a large learning curve. I tuned my 08 with the Vararam and gained 24 rwhp/27 ft-lbs over stock on a dynojet. The throttle is much improved and is a blast to drive.
