custom tune and warranty question

ok I have an FS CAI and I noticed my fuel economy took a bit of a hit... oh well. But now I want to get a custom tune. What would this do in terms of the warranty I have from Ford, the 3 year/36,000 mile warranty... I know it could already be voided due to the CAI but would adding a custom tune be noticeable to dealerships or?

And any advice on where to get a good custom tune in the Southeastern MA area... I heard it's best to go to a place with a dyno so you can get a true custom tune. Thanks!

Its best for warranty people, so get a "cookie cutter" tune on an interface. Xcal1 or 2...so you can switch whenever you need to.

The dyno shop tunes are best for when you are all paid up IMO.

It's locked to your vin and will only work on one car until it is unlocked by returning said car to a stock tune.

I take my car into the dealership for oil changes like every 3 to 4 months. 3k or 5k depends...will they trip out if they saw that my car was on a tune? i dont want my warranty to be voided... how will they know i have a tune on my car. do they check it everytime i would come in for an oil change? im sorry but im a newbie at these things...

I do not take my car to the dealership because

1) It takes way too long.

2) I can get it for 5 bucks less elsewhere and get it done in 15 minutes.

But I don't think they hook your car up to the computer unless you are throwing a code and ask them too. You should be fine.

I have the automagic transmission also, and its amazing what a lil kick into the ECU's rear will do for your shifting. Besides the extra drivetrain loss, I am amazed at my car now when I get in it, vs. dang this thing shifts slow.

If I didn't have a warranty I wouldn't deal with dealerships...

I'm definetly going to look into the XCal2... where do you plug it in to tho?

oh yea and can i still use 87 octane or would I have to switch to something higher?
