Cold start up idle issues

[MNSRT]

Ok, so I have been having this intermitant problem since I installed the mopar longtubes, throttle body and tune.

On cold start ups if I just start the truck and let it idle the truck will start to run rough, idle slowly drops to around 550-600 rpms and when you try to give it gas there is little to no throttle response. If you blip the gas a few times it will start to idle up but you can hear some popping/backfiring through the intake.

If you shut the truck down and start it back up everything is fine.

No codes are present but IMO the truck feels slower after I installed the above mods.

Truck is an 05 RC with Mopar long tubes, catless mids, roe TB, tune from torrie, 172 thermostat, Mopar CAI

you honestly should have a air/fuel guage to get a better tune.
also have you emailed torrie about this situation?
but with a air fuel meter, you can get a pretty close approximation at wide open throttle of how rich or how lean the truck is running,
either that or you need to find a dyno close by and do a run and get an air fuel meter graph for torrie to look at , and modify the tune

That's what I was thinking so I just installed a wideband this weekend. I haven't had much time to get I out and mess with it. What's the ideal ratio at wide open throttle? 14.5 or around there?

Thanks for the input!

13 or below, do it if you can uphill preferibly in third or fourth from as low an rpm as you can and on a deserted road as much as possible, watch the guage from beggining to end, and if you can write it down at every 1k rpms
then get with torrie.
but remember at idle or at a steady cruise, the air fuel is gonna try to acheive 14.7 , dont pay attention to it then, only at wot
