215/215 106 LSA start up on 07 5.3 avalanche

[limitless]

the truck starts fairly fine the first start up of the day when cold but once warmed up you have to floor it to start it what can i change for this? I've played with the timing tables that i know to do, it seems like maybe its a enrichment problem?.. I don't know, and then what can i do for the throttle follower? when i rev it in park or neutral it dies a lot of the time after i let it come back down from the free rev.
I Have it running good at idle and during coasting down / in gear etc ..
Thanks in advance

I have nearly the same issue, 2007 Z71 comp cams 212/220 114, long tubes, CAI and ory. I use a little help as well.

Under Idle --> Airflow --> Startup Airflow

Multiply everything in the table by 1.2 from the 133 coolant temp line down
The increase any numbers above to equal at least what you new number is in 133 line

This should fix your problem

You may need to adjust the Airflow Final Minimum table if you have a rough idle or bucking at low rpm cruising


Cheers!

since i have a smaller cam should i multiply by a smaller number? I just did my swap about 35 miles ago. Today when turning into a parking lot it stalled this is the only time this has happened. Should i just make changes to the idle tables? I havent adjusted anything there yet. It idles about 550-600 rpm with A/C on or off. What should i be at?

Why are you running a 106 LSA cam in an injected engine?

It's pretty low on duration, so even at a 106 LSA he's not running a lot of overlap.

You could try 1.15 instead if you want to

You can look your idle speed up in the table under Engine --> Idle --> Target Idle Speed

True but what a poor cam selection WOW.

Why do you think this is a bad thing? That cam is a torque monster and has a high DCR. Its perfect for a heavy rig.
