More fuel = more boost!!
As suspected (lifter)
Can see the cam lobe. (One all the way in back)
Pull other head and pull cam
More fuel = more boost!!
Pull cam, lobes ground down (see lip)
Put new cam in, new lifters and put back together. Then the final step

You don't use ls7s?
This one I didn't. LS7's are higher I believe. I may be wrong.

We had one not long ago that ate the cam bearings slap up.

120 with trays. Cam has to be changed
A whole lot more than having him to the DOD delete. I had Kevin do my DOD delete and I have gained 2-3 more MPH. I have a 2009 Tahoe.

Can't use dod cam with solid lifter . that's what I was told but I have never tried it. The ramp rates are different and will throw cranking compression off.

I heard TSP has some badass replacement fuel injectors.

Is this problem inevitable with these models or is it due to say, how it's driven or towing heavy loads?
Tsp has been in the LS game since LS was born. SD prices on GM parts are super cheap. Love can't compete if you have time to wait 2 days. Gmpd is next and they are in Charlotte.
