I'm sure there's a thread here somewhere but I'm on my phone and couldn't find it. I've seen the 4.8s take 20lbs+ so I'm thinking of starting off with 10lbs and 93/meth.

What kind of luck has everyone had, I don't beat on the truck much and it's only drive on the weekend.

More then pistons can handle.
The intake is plenty strong.

i"ve noticed that alot of people started out at 8-11# and the more kits that are sold the number are starting out higher i feel. it seems like most people with new kits are starting out anywhere from 10# and up to 15#. im gonna be running somewhere around a max of 20ish# here within the next week hopefullly i also beat on my truck not sure if that helps or not?

Lol. Read wrong. Bad habit add or remove letters while reading.
Happens slot when a type.
Anyway. With solid tuning, be simulat to the 4.8.
It all relys on the tuning and wear/tear on parts planning in using.

We have seen engines hurt at low boost, bad tuning.

Trucks got 130k on it. Kept looking and seen multiple threads on 12lbs so I'll go for that

If the tune is good, shouldn't have a problem with that. I'm at 10-11psi with 140k on my 5.3 and it hasn't missed a beat. But like said above, 5 psi and with a bad tune can blow a 5.3 pretty quickly.

Patrick G from Victoria will be tuning it. No worries about the tune
