I would rather do it myself than take it to the dealer. The ones that really take the time to do it right are few and far between. My dealer did mine after I changed the header and a/c, it ran ok but when I noticed it was running very hot, I bought the software ($50), cables ($50) and checked it out to find the heat management was "OFF", and my redline was set to 7000 rpm! I think the dealer just used a canned download to flash my ecu and didn't spent the time to Smart Tune" it like the service manager said they did. Dealer mechanics are under the gun to do it fast, under the prescribed time. I changed A/F ratios and retarded the timing a bit and it runs 20 degrees cooler, the heat mgt works and my redline is now 5800, and my gas mileage is still around 45 mpg.
I say, do it yourself, then if it still runs like crap, find a "reputable" tuner. (Check those O2 sensors to make sure they are in the correct hole)
