Looks awesome. I'm excited to see the results.

 

Very nice results, glad I didn't pull the trigger on the cx cooler I was looking at. Do you think there's enough room behind the grill to fit the 4.5 inch core treadstone makes?

 

Nice upgrade man. Thats my favorite GMC front.

 

Nice gains, see how that helps out on the back half.

 

I haven't been to the track yet with the caltracs and intercooler yet, but I've been messing around on the street and kinda have an idea why the truck may not be picking up in the back half. I've been watching my boost gauge, and 1st gear I'll see 8psi if not a little more, second the same, then 3rd gear, it barely kisses 6lbs. I'm assuming belt slip? I have a LIGHT mist of belt dust around the pulley. My other thought is possibly the boost is bleeding off in 3rd since its in that gear the longest? My cam isn't meant for boost and has a bit of overlap as its a TV2. Any way to confirm that I'm definately getting slip?

 

What rpm are you hitting in 3rd. Remember your boost is rpm dependent. Log it and compare boost at the same rpm. Just because you're at the top of the track doesn't mean it's the top of the gear
