So far.... Nothing but Problems

I did get a custom tow tune at 91. In the past i have been able to puch teh timeing to 2.5 without problems. Either way the point is that the new grypon will only advance it 2.0 in .25 incerments.

So does it advance the same as the manual states? And i only advanced it .5 up and so that would say i was running 88 octane acording to the manual. 91 should more then run on that with no problems?

Im so confused. I had my favorite presets in my ver 4.xx.xx and now they dont go the same into this one. Any custom tune ends up jinxing me even if i jsut mess with tire size

That should have no effect on how the engine runs.... Just shift points right?
