Default Blown Avalanche
After lots of indecision i'm finally getting blown. I bought a tvs 1900 to force feed my 5.3 cammed avalanche. Wondering what to expect hp and et wise? My goal is to run 12.5 or 12s on DD.

First, expect to replace the 4l60 sooner rather than later. I would plan for 400-450 hp depending on the dyne.

By the way, welcome to the club. Please surrender your wallet at the door. You won't need it again.

Don't know about HP wise but I will make a guess of low 13's. Get a stall and I would say into the 12's.

Those av's are not known for being the lightest of vehicles LOL

Should be close, but I don't think your gona get 12's. Mid low 13's imo.
