New to this forum but not the car world. I have a 06 GTO & TBSS. I will be installing a mp112 on the GTO with in the next few weeks and wanted to know if anybody could guide me to an area when I could work on a base tune to just get car going. Stock cam and heads with Kook 1 3/4 catless mids and may just start with a LPE intake until I get everything else situated. The trans is also stock for the time being but have plans for a build with a yank stall. Car currently has a Modern Muscle tune for a while back before I did headers and a fast intake. Any help or direction would be great. Once intalled I will have a wide band and all the proper gauges to keep an eye on things. (areoforece ect.)
