I hope this finds everyone well. I'm looking into tuning my 2004 Cadillac Escalade EXT. I have acquired the otofix model with the EEprom clip and OBD 2 wireless adapter. I was using ECU text tuning hardware and software when I was working on a 2015 Subaru BRZ which I supercharged never downloaded it. But I must say I was happy with the tune and looking into it I didn't realize it was a such a complex thing that I had done running on e85. It was sweet there. Any suggestions anyway might have. Keep up the awesome work. Stay happy my friends
