EPC Issues

[Airnautique54]

Yes according to JHM (bugged them with questions for months before I pulled the trigger). I was super nervous as well (mine had 100k miles on it when I got the tune), but I've been up to date on maintenance which sounds like the most important aspect. Now that said I don't routinely run it up to redline nor track it so the car is pretty babied, other than enjoying coming out of some rural road twisties in 3rd

I had to replace my intake manifold to resolve the EPC and CEL. I eventually decided to deflap and tuned it out with JHM. I already had the tune, just added the flap delete.

I know some people think JHM’s tune is too aggressive, but I believe that’s mostly reserved for their 93 tune. I’m running the 91 tune with 93 octane gas and haven’t had any issues.
