2006 Chevy Silverado 5.3 startup issues.
I've never tuned before or used this software, my truck has a problem starting when the engine is warm, it takes multiple cranks till it fires. However, when the engine is cold it starts on one crank.
2006 chevy Silverado 1500 4x4, 150,000 miles
4 in lift
off brand Holley intake manifold
cold air intake
Long tube headers
Diablo monitor and tunes (made my truck run like crap)
I'd also like to add a rev limiter on my truck if that's possible with the tuning software.

I would smoke test the intake for starters. Then fuel pressure at the rail when hot. Your truck should already have a rev limiter. 6000 rpm unless the Diablo changed it.

Posting your tune helps alot.. A datalog helps even more.

Have you read the tune off the truck yet and saved it to your PC?

Little google goes a long ways..
Read this all the way through before even opening your software.
