Tuner recommendations Hello, my 2002 Z28 needs a tune to run better. Currently, it's running a stock tune with headers, Secondary Air Injection deleted, and rear 02 sensors are deleted, so it throws engine codes for them (P0410, P1133, P0160, P0158) So I am looking to find a tuner to give me a tune to fix these codes and stop my headers from "leaning" out my car, not looking for a full dyno tune as I see that as a waste of money If I plan on camming the car and having to get another dyno then, also strggling to find a local option (southwest wisconsin) as I've never had to seek a tune before, so I think my best move is to find a remote tuner, to those who have gone with a remote tuner before, who do you recommend? I've heard a ton of good and bad things about many different online tuners; looking for opinions/recommendations from people who have had their cars remotely tuned before. Thank You!

I see you're in Janesville, I have some family up there. Not that you asked or care, just sharing.
You're not THAT far from the multitude of Chicago options, Speed Inc is a big name. There's also Juiced Motorsports in St. Charles, and Precision Tuning that a friend of a friend has used with success, that offers remote tuning (https://www.facebook.com/share/1GaEU...ibextid=wwXIfr).
Also Nickey in Rockford, and Koza in Woodstock. No experience personally with either, but they both have a pretty good name.
You could also go the play with it yourself route via OBDX Pro and PCM Hammer/Universal Patcher if you wanted to do a little experimenting. I plan on messing with those once my OBDX shows up, just for fun. Plenty of way more experienced guys will chime in here I'm sure, but just a couple ideas, hope that helps!
