Hello I have an LS1 B pcm on a 98 Chevy truck with the l31 engine. I've been adjusting warm start, 168F plus. The Truck always started well but I'm just looking for a louder/ more solid start. I've adjusted startup air which now makes the truck hiccup when starting. I've lowered initial fuel prime and cranking fuel which helped but still not quite there. Anything else worth looking into?
