Actually the correct (WIS) way to do it is to activate circuit 50 at the fuse box which is what I did. No fuel, no spark, no codes, just turning the starter with the battery on a charger.

i'm 120-122 psi on all cylinders with a cold engine. fuel pump fuse is pulled, of course.
Before and after my dyno of 600+ rwhp. Pulling heads soon to replace my head bolts with ARP. I will inspect the heads and see if there was any problems.
Kleemann Camshafts would effect my compression?

Dyno's don't mean your car is/isn't a beast, they're made for tuning Pre/Post mods.. The mighty Alan & I ran our cars at same High reading DynoDynamics @ Autowave. He had every mod possible at the time & ran 10.7x 1/4's w/130+ Traps he ONLY made 590 rwtq.. We both made same exact 565 rwhp but my rwtq was 700 on same dyno, same tuner OE, same dyno operator, same weather etc etc Did it mean my SL would run 10.7x too? Absolutely NOT... Just a tool to tell you if you're making progress w/chosen mod path or not etc..
I've learned the hard way & seen too many
Dyno #'s over the yrs INCLUDING my own..

Radical camshafts can lower compression test results for sure.
Cold motor, sounds low. But, then again you have those cams, and these motors probably have larger clearances so you don't destroy your motor with some high speed autobahn action.
I wonder if Shardul compression tested on a warm motor?
