How long for a tune?
How long for a tune? I know this has been hashed out at least a few times, but I'm trying to manage expectations here. The same shop that is tuning the car did all of the engine work.
Relevant info:
-installed D1SC boost should be ~7lbs
-installed kooks headers + true duals
-deleted EGR and AIR
-replaced a bunch of gaskets
-Fuel is a racetronix pump + hotwire through AUS 65lb injectors
Car is an M6 with ~145k miles on the stock LS1
The car started being tuned, but they can't get it to idle so far replaced the IAC, TPS and a rotted vacuum hose behind the intake. I know that it's a high mile car and things can happen, how long would you expect a shop (procharger dealer) to get something like this sorted out?

With the MAF, sounds like there are no problems with the WOT tune, but at idle when warm it'll stall out. They've already had the intake off and it sounds like that was how the found the dry rotted vacuum tube, but that didn't help.

Since you are paying someone else to do work on the car you will be into this for alot potentially.... they own this problem as the car ran and idled fine before their install and tune. I would try to come to an understanding that you aren't paying for diagnosis and repair of an issue they created with the install.... Install cost and tune of course should be paid. You really are at their mercy though and they could charge you extra labor for diagnosing issues from their own work/tune....

I totally understand. Not sure if it matters or not but that shop and my guy are about 10 miles apart. Just thought I'd throw it out there in case

Stock cam and low boost. Also since i didn't mention it before, the car ran great when I dropped it off otherwise I wouldn't be boosting a high mileage LS1. It sounds like at this point I might not be crazy for thinking > 1 week for a tune is getting a little on the longer side. Per the invoice I've got they're also charging me $950 for just the tune which seemed high, but I figured for getting a great tune done quickly it'd be worth it...

Probably don't have the vacuum line to the ProFlow hooked up right as it is very hard to get it to idle if that line is leaking.
Did they upgrade the injectors, switch to a new MAP sensor?
If the injectors were changed and are substantially larger,
If the injectors were changed and are substantially larger,
- Hopefully the injector data has been entered correctly
- If the data is correct, and it's running rich at idle, they might need to drop the minimum fuel milligrams in the transient fuel tab (at least that's what I did to tame my 127# Bosch in HP Tuners). Stock value was 0.041 and ran rich no matter what I did to any VE(speed density tune, 3 bar) but changed it to 0.020 and it cleaned right up.
