Program after Header install
I bought a set of Hooker Headers from Summit Racing that were delivered today. I called a shop to have a quote on installing them which I knew would not be cheap and they wanted 450$ to program it after the installation. Iam okay on the quote they gave me but thought this program price was a bit high. If this is what it is then I am okay with it but wanted to see what others that have had this done thought. Thanks.

No worries, that’s what I thought.
Then after that tune and header install, I had a cam put in an that was another $550. Go figure, I wasn’t real happy about that but…..

If they're just turning off the rear o2 sensors then that is a no go for $450 and you need to go somewhere else, BUT if they are recalibrating your maf curve to adjust fueling, then that is a good price.
Believe it or not, some places have charged $450 just to disable 4 codes, that is NOT TUNING, it's 2 minutes worth of work at a cost of $150 in credits.

Something to bear in mind are the sensors ready. Are you in an area that requires you to pass emissions? I know in Harris County, TX, you can't have more than one sensor in the "not ready" state, and to get it there requires a tuner who knows what they're doing. I went through this on two previous Corvettes (my 2008 Z06 and my 2010 ZR1). There's a tuning trick to bypass the conditional testing and just force them "ready".

As stated, need to make sure that the after install price, is to tune as well.
Hence with long tube headers, the post cat O2 sensors are not used, so you have to go into the tune to turn then off.
Next, is since the long tube headers make the motor gain more power by increasing the amount of exhaust that is pulled from the heads,
The tune has to be redone to keep the engine from running too lean during WOT (when the system is running open loop).

You wont know theyre the real deal until someone else scans your tune, you'd be surprised how many praise shops that turn out to be hacks when someone skilled looks into their work. Not saying this shop is like that but you need further investigating before you can fully trust a shop to say they did everything perfectly.

Thanks for all the info. I live in a non smog-test county, and this mod is in my future if I make changes to the exhaust. Good to know that the old in-line resistor to the O2 is no longer done.
Great forum!
