Hubby is a wild man !!!! Mine has boosted 30 it was big fun, really big, How is hubby's running now ?

Thank you for pointing that out. I didn't really think about the temp being on visible on the video. I thought that boost supposedly went up with temp due to pushing the same volume of lower density air. I have limited mine to ~23 intentionally for two reasons, one, the 2.5bar sensors run out of control range above that and , two, the stock turbo runs out of its efficiency range. I'll double check, it is like 68* in the morning and 100*+ in the afternoon here and I think my boost will still go to the same spot. I'm actually running half ethanol with almost double the stock timing up top. I dunno what kinda power that results in, but it sure will burn tires from a roll. Cue the obligatory knock on my F-Hawks by SS Fan...

can you run ethanol/water-meth without a tune? or would I be better off tuning for it?

I think you misunderstand. Half E85, half gasoline. Not meth/water. The higher effective octane of the ethanol fuel allows me to run a timing that might result in much knock or detonation with regular gas. (real power is in the timing advance, not just the boost) It must be tuned for. The injection constant must be modified so each pulse delivers enough fuel to meet an increased fuel/air ratio of ethanol. (9:1 for just ethanol alone IIRC) Ethanol contains ~20% less energy than gas, so you must both deliver more fuel and advance timing to gain a benefit from it. I'm not sure if Superchips will let you see and tune the parameters you need.
