Ok guys, I'm going to be putting a GM Hot Cam in my 02 Z28. I ordered a tune from Solomon @ lt1pcmtuning, yes he does LS too. Ran into a bit of a bind as he normally asks for fuel pressure reading with vacuum line off of regulator, which in an LS car does not apply. So he asked me for a vacuum reading at idle. (Injector table is scaled for vacuum). My problem is I have not done the cam swap yet as I was hoping to have tune first because from what I have read, the car won't idle with a hot cam in an A4 without the tune. I don't want to do the work and then have the car stuck there, and if it doesn't run I can't get vacuum anyway. I found 1 post about someone having 14 inHg with it but looking for more input to hopefully at least get a baseline tune to get it running good enough to take an accurate measurement and fine tune from there

Thanks in advanced.
