I was wondering about that, they are wanting like $250 for the tuner and how often will i really use it. there is dif tune depending on what you want, i always use 91 octane but at time i would like to save gas, how much gas will I really save and is it worth spending $250 on a tuner so i cna change it to save the gas. Think i will just get the intake with the throtlebody spacer and do exactly what you said and let a professional tune it.
let me ask you this, in the doc for this tuner it also says you can change the tire size so everything stays accurate, reason im asking this is i do want to put 20s on it but at the same time i want to keep some side wall for better performance so i was thinking of going with 20's and getting bigger tires, total diam is like 27 and 3/4 inches, thinking of going to something like 29in or as close to it as pos, what you think about that?
Again any comments would be great!
