Give me a call at the shop if you'd like. Ask any questions and address any concerns you may have with tuning whether it be "mail order" or otherwise. My typical pitch: If you like what I have to say, great! If not...that's cool too!

Tim would you say a Tune is needed with a O/R X or H? From what I've researched the COT protection only kicks in on decel? The worst I can see happening is you run a tad bit richer and a check engine light. SOme tunes like AED and such have specified they dont change anything just remove the Check Engine light? Input?

You, you will need a tune when you delete the cats. If not, the car will run open loop and just dump fuel trying to cool the cats that aren't there anymore. You will run rich and get horrible gas mileage and a putrid smell.

Your talking about COT protection. It only happens on Decel. Rear 02's do not control anything. they have a voltage reading of .1 to 1. The front Wideband 02's read .1 to 5 volts they would tell the ecu to run in open loop.

Im not speaking for the rest, but a good tune has more done than just turning off COTP & nannie lights on these cars with no cats. Thats just one part of it.

Thats why im asking Tim to chime in. I already have a tune. just needing to know if it needs another one. All your doing with the exhaust is increasing flow after the combustion process so the power gain comes form the flow not the actual tune.

So nobody else has an opinion about just staying with the Bama tune if I'm pretty much stock?

And D- if Ford determines that it's not the tune and the tune didn't cause it, then they can't void the warranty for having a tune if the tune didn't cause it.

I'm not worried about that- just saying.

I understand. If you currently have cats with your tune and will be removing the cats, yes your tune needs to be updated.

If you're happy with the car and the way it runs, stick with your bama tune. Axelbacks do virtually nothing for performance enhancement, so your car is essentially stock with a tune. Switching to another tune is an option but not necessary.

If you just want more information about the status of how your car runs...datalog.datalog.

Agreed 100%.

Yep that's what I'm doing. I just got off the phone with Bama.

I'm going to see what they want done and send it to them- and then do it again when it's warm I guess. I'm not sure what differences a datalog at 30 degrees will have that may affect the tune at 100.

Yeah- I don't mind being stock with a tune for right now- it still doesn't "feel" slower than my GTO did with 430 (fat pig and top end cam). I'm saving for a s/c and doing all my power at once. :burnout:

Sadly, they still will. A dealership won't be able to go as deep as Ford themselves will into determining the failure, but knowing that you've tuned the car, even if it didn't directly cause it, good luck trying to convince them otherwise.

Car might add/pull a little timing, but not much.

Do you have an auto or manual?

Isn't the law that if they determine it wasn't the tune then they can't void the warranty for something they just said didn't cause it?

I don't see how that's right. Either way I don't have a warranty other than factory.

A6.

Downloaded everything from SCT I need to datalog.
