I have to say, ive only had one car remapped, my current toledo, and I got it done at auto tune in ballymena, i went to them because one of the cars passing through our garage had been remaped there and the owner was happy so i went to them, they were helpfull and friendly, had the car in and tuned and out, runs on the dyno and everything in an hour including a test run out, i was pretty impressed, more impressed with the results than anything, 110 on first dyno, 141 after remap. they took into account the decat and filter and tweaked to suit. and they answered all my questions about stage 2 on the car, if and when i plan to go ahead with it. £180 was also substantialy cheaper than others.
Came home, went out to work and 5 hours later went out and the car drive for about a minite then piles of smoke and revs and mess. called out the recovery lorry, waiting for it i started her up again and she was fine, however put her on the lorry and went home, phoned them in the morning as it was more than a coincidence that my perfectly reliable car went pop 7 hours after theyre remap. turns out the fuzzy logic used in the ECU was still using the "old map" and not the remap data, so it shat itself and didnt know waht to do, i can understand this, its ****, but it happens, it was a 1/1000 chance it was going to happen, unfortunatly it did, this happend once and hasnt happend since the car has settled
basically Im saying that I am happy with auto tune and id reccomend them to anyone, this was my experiance with them and regardless of a fluke **** up on the cars part, they were prefect
