Also, I have not updated ISO yet because I wasn't sure how return policy will be at Burgertuning after cutting the 2 diodes, so I have not touched this yet.
Let me try COBB first and then I will see which tuning I want to stick with.
I don't understand how you can even make a comparison considering your G5 was clearly not setup right. Back to back variations of 5psi and trim flatlines are not normal. I suspect you input the wrong settings either via drop down or on the user adjustment page. The G5 plus Cobb flash is really the best of both worlds, but it seems like you for some odd reason have made your mind up... The G5 alone will spank the hell out of a non protuned Cobb, especially on E85. If you want to get the most out of the tune on Cobb you need it custom made for your car or you need to do ATR.
