Just wondering how's this done? Does it make more hp? just curious. thanks __________________ 02 crew cab 2500 HD lb7 AEM Brute Force Intake 5 Inch Straight pipe PPE Boost Valve Trans Temp,Boost,EGT gauges 5% window tint cranked torsion bars Diablo predator intake horn mod New injectors

If I remember right the max'd out truck was running stock rails and fittings, dyno'd 1100+rwhp on fuel only too. __________________ 2002 GMC LB7 Cognito tie rods and braces, SC stage IV 1056 converter, MITUSA lift pump, RDL up pipes Homemade twin turbos, stock IHI over s475 EFI live tuning from IdahoRob http://www.atptrucks.com 12.34 @ 108.7mph Last edited by Dmax15 : 10-25-2009 at 08:11 PM.
