Rocket Man's 2008 Bagged CC Silverado Build AKA "THE MACHINE"

[Rocket Man]

The guys at BlackBear must be busy and working late. Justin sent me my tune files at 8:00 tonight. I loaded them into the autocal and will install then in the morning. I can't wait to see what this 4.8 will do with a good tune and a good IAT sensor. He told me he's never seen one fail and not throw a code like that one did. I would have never known it was fried if he hadn't alerted me to the reading he saw. Anyway it might be awhile before I test the tune since it's supposed to start raining again and I don't want to drive this thing in the rain and have to clean it again. Because show truck lol.

I'd also be curious on what the 4.8 is capable of. I also have it in my Express van.

Boost and lots of it from what I read.

I'd be able to cut my travel time in half!

If you do it correctly.

Here it is with the 26 x 14's. He said he went to some 28's after this and then to the ones that are on it now. I might get something like these in the future if I can sell the ones on it now. Crazy since they're over $6000 a set. I'm pretty sure he was trading them among his buddies in Cali but still...

Had a 4.8 in my '03 and was pleasantly surprised with it. I'm sure a BB Tune will wake it up nicely.

Nothing wrong with the 4.8. BB tuned mine nicely. It may never outrun the 6.0/6.2L, but it sure is fun to drive.

As long as it's a v8 it's all good in my book. Had a 4.7 in my Dakota and loved it. Much lighter truck but it was quick.

I used to have a 2002 RCSB 4x4 lifted with the 4.8 and a 5 speed. Full Gibson exhaust and headers, it was surprisingly quick.
