Ok so I got my maf cal installed and then i decided to take it on a drive and when I went to put my foot into it at 4000 rpm it kinda bogged down and stuttered and it felt like the motor was trying to get through this. With using the supplied software and the cable to connect it to my computer can i tune this or do I need to take it to a shop that has a dyno? Will elevation and the weather affect the tuning. Also is there a place were I can find pre tuned maps just to load onto the new piggy back system? Any recomendations would help a lot
