Cam install help I just wrapped up a cam install yesterday and I can't get this thing to idle or even run right. The cam is a tr224 on a 114lsa 563lift, nothing extreme. Also put on ls6 ported oil pump and ls2 chain. I think I have some misfires but I can't pinpoint it to one cylinder. I've tried different tables and histograms in hp tuners and I can't figure out how to log individual cylinder misfires 
Im pretty sure it's nothing mechanical, dot to dot. What's the trick. I drilled the tb hole out a little, I adjusted the throttle screw, reset the tps sensor, raised the idle to 950 from 68*f on. I also bumped the timing up 2* in the idle cell. IAC position is at 160, how big of a hole do I need to drill? I rechecked every connection, coil packs, plugs, wires, pcv, oil pressure is good. I'm also getting random misfire codes and map high voltage code. Sorry for such a scattered post, I'm just going through these problems as I type. When I drove it aroud the block it sputters from right around 1000 rpms to 2500 rpms. Any help will be very appreciated.

First of all, quit drilling holes in the TB.
I'm not enough of a HP_tuners guy to know all of its capabilities: Specifically, can it even diagnose (I know not every version can).
It can be scary, but there are files available at the HP_Tuners site for stuff very similar to yours. READ ALL THE WARNINGS THOROUGHLY!
