How about a meth revision.... my LME meth tune is barely noticeable over my 93 tune. I even turned the meth off for a pass or two and watched to see if it pulled timing or if it wasnt getting enough fuel. No problems and ran comparable to my 93 tune... So if your planning on going meth, no offense to the Good guys at LME but someone willing to dial it in from logging is a good bet. Especially if you don't want to have to take a vacation to Michigan to have LME dyno tune it.
