Tuned my buddies Turbo 5.3 on 2bar map. He decided to convert it to E85 and switch to 3bar and have a shop dyno to it. The OS didn't allow for 3bar so I understand the voltage offset being changed, but if you compare the two nothing was really changed. Changed for bigger injectors, timing table only changed at wot, value for Stoich, and Map table if you compare the difference between the two tunes just looks like a hack job. Figured it would be bigger difference between before and after setup. PE stayed the same. Main concern is why the new Map table looks the way it does. only 1-2% difference between 100kpa and 200kpa with big drop in the middle of them. What's some of your opinions on this change.
