How much power do you think the L5P can hold? The threshold has been 650 imo but obviously weíve seen more for drag trucks and smart tuning but thatís pretty much where all bets are off.

Hey y’all should not be running any bio mix fuel in these trucks or anything with a dpf
It’s a sure fire way to clog them up quick
We found out the hard way that one of our guys was filling up his welder with race trac fuel which here in FL they are bio blended and it munked it up

Unfortunately, thats all thats available at the pump in some areas.

In CA, the pump's say may contain up to 20% bio.

I should also mention they technically ďcan run up to b20Ē
We all know how engineers are though and how it looks great on paper...like the rest of the emissions

Has anyone used any dpf cleaner products with luck? Most everyone here probably just deals with the problem the ďotherĒ way

So basically like an lbz...

I think the material removed from heads will cause issues with sealing at high power levels. I've heard GM locked it down bc they know the weak links and don't want any bad press floating around until they are figured out. Then we may get the tuning options we want...
