2005 GTO inTune

[05GOATLS2]

I have a 2005 GTO and thinking about purchasing the Itune. What type of gains can I expect on the 91 octane tune (max octane we have in CA) and more importantly can I adjust line pressure, shfit points, and torque management? With this throttle by wire this car has the most torque management I have ever felt before and is really holding it back...

Sorry forgot to add it has the 4L65E.

the tune will add a solid 20 rwhp tot he 05-06 LS2 GTO models, and TCM support for the 4L65E will be added very soon, and will allow for WOT and part throttle shift pressure adjustment.

Thanks
