I know this question keeps getting asked but I can't find the answer to it.
My 04 RalliArt has about 115,000 miles, now if I get the RRM ECU piggyback, would it be a problem considering my car is high mileage? I'd also like to see what everyone else's experience is with it up until now. The gains I understood but since it came out like 10 years ago, no one had cars with over 100,000 miles which begs the question I just asked.

I bought mine with 162,000 on it and ended up getting it tuned instead of the piggyback as recommended on here. The piggyback is old technology. I spent about $300 I think and that was including the $100 OBD2 plug to attach it to the computer. Best investment I have ever made on this car. I am about to hit 200,000 and have had no issues or regrets from the tune. He even updated the tune when I added the larger throttle body and intake for free.
OttRalliart05 was the one that tuned it for me. Great guy. I pm'd him and it took a little while for him to respond. He said he is not on here much and to contact him here: ziptuningcdn@gmail.com
