Hah no, I saw that and did load the tune before I started tearing stuff out. It took the tune, started and ran fine without throwing any codes. I installed the new intercooler line and removed the throttle valve. Then moved to the egr and had the issues removing the manifold side studs. I decided to start the truck to warm up the bolts, that's when it threw a code for the intercooler throttle valve. I thought maybe it could be because I had it removed and not the egr?
The questions I had were whether I could drive it like that if I can't get those studs out.
Also-with the tune, I definitely have to remove the def system correct? I thought that's what I read but wasn't sure... So I continued pulling off the exhaust so I can install the new pipe.
Am I in trouble?
Ah, good man.
No, the throttle body code is completely independent of the EGR. Once you program the EGR out and unplug the wire harnesses you're good to go and can finish the whole delete at a (not too) later time.
Not all, very few actually, tunes are set up to delete that butterfly valve. I can't speak for the SCT, not familiar with that tuner, but I think it's safe to say if you're running the tunes that came preloaded it's not gonna support the valve removal.
Yes, you have to remove the DEF and the CAT from the exhaust after tuning. The DEF fluid tank and associated junk can stay installed.
As far as driving it goes, with that code you're probably gonna run into all kinds of issues, and from what I understand you have some of the EGR stuff out but not all, so I wouldn't drive around with a half removed EGR.
