Rough idle

[Bagoftrix]

Ok...so now that I have it back running with the new additions, I'm having trouble with rough idle. I was expecting a different idle with the much larger cam, but I can't get it to sit at anything above 400 rpm if I'm lucky and its warmed up. It has a new chip in the ecm to operate the new system. Do I need to adjust the idle control module in the throttle body to better suit the change??? These are some of the changes that I've made...

TPIS MiniRam Manifold & Corvette Fuel Rail Kit

- TPIS 52MM Throttle Body

- TPIS ZZ409 Camshaft 226/226 .520/.520 Lift 112 LSA

- Dart 180cc Pro1 Aluminum Heads w/ Guide Plates & ARP Rocker Studs

- 24lb injector Set FlowMatched

- Aeromotive Intank 340 lph Fuel Pump

- TPIS Custom PROM

- Comp Cams Ultra Pro Mag Rocker Set

- Hardened Push Rod Set

I found the issue. My tuner found a list of things that need to be done to dial in the timing and idle with the new chip. If anyone is interested I can post it tomorrow when I take it down for tuning.
