I lost all faith in Comp when they sold me the wrong cam
for my 5.3.VVT I had a long talk with them before i ordered it.
My truck ran like ****. I found out the cam was designed for
a 6.2 eng. I had 3 diff dyno shops try to tune it, with little
success in getting it right,

 

I'm with FFDP. Comp has huge quality control right now.


I'm running a TSP 220r with High Lift .600/.600 and I've ran 3000k and I'm going to a 3400-3600. I have a guy who also did this (how I got the low stall anyways) and he loves the truck so much more.

If you are towing with this, id recommend atleast 3000k stall from Cirlce D( have perfect stalls set up in that range to town with) and a set of atleast 3.73 and up.

Have an 99 Silverado with only 3.42s and towing was ehh. Have my 01 now and even before the cam 3.73s helped huge!
