FLYLOW My ? Is, when flashing back to stock do u get the same oem tune with same exact codes/#'s/map Or is it a copy/mirror/similar to the oem tune? When i had my gc with a br tune the oem map was lost completely, they just had a very similar one in the hand held that could be loaded up/flashed to stock, dealers couldnt tell. Only way to tell was to send the ecu to korea and they would see the map codes wouldnt match the oem tune

FLGSVT If the ST is anything like the the 2011 and newer mustang then they have a flash counter and they log if the car has extra flashes.

Tunes CAN ruin warranties if its ruled that it cause the failure but having a tune does not simply ruin the warranty. The tune can be removed, and no dealer has the equipment to tell if you have tuned your car if you flash it back to stock before you take it in for work/warranty work. if your ECU was sent to ford then yes, they may be able to see it was tuned at some point, but with the tools available at dealerships there is no way to tell as long as you have removed the tune before taking the car in.

If you are SMART, then having a tune is fine and you shouldnt have issues.
But if you show up at the dealership with your tune on the car and the flasher in your glovebox then yes, its a possibility they could deny coverage on issues. Even then, they have to prove that it caused the failure/problem

acbauza I bought this tune and was nervous as I know of a few who melted their STI engines with tunes. Anyway, this isn't an STI and Ford did a great job with the engine. I bought my tune with the 93 octane option and immediately noticed the car is different. I took the car to the track last October as I am an instructor with the BMW club and surprised a number of people with how fast the car was stock.

Now it has the tune with the rev limit @ 6200rpm and a green line filter along with a Steeda rsb. I took it the other weekend to Summit Point and WOW! I pulled on many Bimmers and some Porsches in the straights, but because I didn't have R-Comps and brake pads I had to give a few point bys. Many though inquired what I had done and they all were stunned. I love the tune and would love to know what it outputs on the dyno, but first I need new pads as I destroyed the OEM pads with 8800 miles. Yep. You read that right. 8800 miles and it needs front brakes. Summit Point is notoriously hard on them.

My friend has a Mustang Dyno and plenty of tuning experience, so we'll see what we can squeeze out of it. Overall the FSWerks tune is just what the Dr ordered.
