Okay, hopefully I don't come across as too stupid but I have a couple of questions. I am ordering a Kenne Bell next week for my 06 Stage 1 Roush Mustang. Getting the non-intercooled 5psi kit. They say they send the tune and you don't have to get it custom tuned. Is this true? My mods are JLT CAI, SCT tune, and 4.10 gears. With the Kenne Bell will my JLT and tuner be useless and can Kenne Bell send me the supercharger tune adj for my 4.10 gears? Thanks in advance!
i may be wrong you will not re-use your CAI, and the tune you will receive is set for air/fuel at rpm so there will be no real tuning for the 4:10 gears. only adjusting the gear ratio options (just like changing tire size) and you have another tuner you can sell on ebay!
I have a KB. You just tell them your mods, tire size and gear ratio . They will set the tune up for you before shipping the kit. I ran the stock KB tunes for a long time before going with a custom dyno tune. Jim Bell spends more time on these tunes than any of these guys who sell tunes over the Web. You will be fine with KB's tune.
