2004 Tahoe Tune 5.3l - w/cam

[WERO Performance]

I'm trying to tune my 2004 Tahoe, 5.3l. I bought a cam and these are the basic specs:

Cam 277/277 @ ½” is 228/228

Lobe separation is 110, valve lift is 588/588


Having a tough time with idle and rolling idle, and after it seem to work better, now it has severe hesitation when trying WOT.

Has anyone worked on a similiar application? I have 2400 stall, Corvette Servo, headers. Haven't made any adjustments on fuel delivery system, but still works good. Have only found stock tunes, nothing that I can work off of...

I will be adding 36lb/injectors, upgrade regulater and fuel pump. Well, would've already done it, but cant find the parts, can anyone help with that??

When you check the tune respitory look up 5.3 not your tahoe and you will find plenty 5.3 with cams.
