Get other things done while you're in there. Maybe the oil pump. Mine was running rough and found out my cam phasers were bad. Had that, chains, guides done and while they were in there, new oil and water pump. Preventative measures. If you plan on keeping it, it might be worth investing a...

I really would recommend HPC. My car has been running great since they worked on it. They are enthusiasts and do a lot of performance work. You can look them up on Instagram and see some of the things they work on.
I ended up later taking my car to somebody more local to me. The shop I mentioned above was just too far to drive. I now take it to HPC (High Performance Connection) and they did a GREAT job re-tuning my car. runs GREAT.
You're welcome. My engine wasn't running right. Had it worked on other places and HPC is the only one that figured it out. They repaired it, put it on the dyno and re-tuned it and now it runs like a beast. Been very happy with the work.
