Yeah, I think so too but I want to see what other people are getting. I'm sending the chip back on Monday and I'm going top request they add about 5% more fuel. Living in the Chicago region we have 10% ethanol all year, I think that may be a factor in leaning it out.
Damn dude. Ur crazy.... 11:1 Better Rich then sorry. Thing is u never know if ur going to get bad tank of gas & here comes detonation. 1100 F be better off. Its how well ur engine burns the Air & Gas that makes the power but u got tooo much air for a Supercharger. N/A cars is o.k. since they can make power by going a bit lean.
