I talked to my buddy; he said he did not mention the 4.10 because I do way too much freeway driving. He wants me to write down what my RPM’s are at 25mpr, 35mpr, 50rpm, 60rpm, and 70mpr. I do drive about 50 miles a day freeway 65-70mpr (work), maybe 10-15 miles city (kids sports). He said it would be nice to have 4.10 but if we do everything we are talking about, I will get what I want out of it (more Power). You said you got more MPG? Do you know anyone else? Right now I get 14-15 MPG, if I just lost 1mpg. If it’s worth the power I will deeply consider it.
