Alright guys we all know that e85 is amazing but what about the guys that only have 91? My car is in sig but im looking at getting a mmr short block very soon and pulleying down :rockon:. I have spoke with my tuner and he says these cars dont like meth because the widebands detect a rich spike from the meth and automatically start leaning the car out to compinsate. Is anyone running meth if so pm me im very interested in what ppl are doing to make up for not having enough fuel. My plans are to build motor and run 800 all day dd. Am i sol or is there a way to get the power i need?
