LQ4 6.0L Dyno Results Just wanted to get some feed back and see what everyone thought about the results I got for my combo. LQ4, ARP rod bolts, TSP Torquer 2 cam 232/234 .595/.598, 243 heads milled .010 with a .036 Cometic headgasket and comp valve springs and retainers, compression should be around 10.8 to 1, LS6 intake and TB, LT Headers 3" collector and 3" y-pipe to 3" SLP cat-back, and a 6spd tranny. It made 420hp and 419 lb/ft torque. I thought it was a pretty good number. Let me know what you think.

No cut out, it had one on it when I bought the car but the install was all hacked up. So I just installed a piece of 3" pipe in its place. Do they really make that much more power? I have heard that the SLP muffler flows really well, as good as just about anything else out there. I am open to any suggestions to free up some cheap power.

Looks alot better than my 345rwhp/350rwtq with my setup through an old th400/4400 stall combo. I made that power number with;
02 LQ4 66k stock short block(180psi cyl compression all around)
PRC Stg 2.5 5.3L Heads w/ 59cc chambers and recessed valves
Flycut pistons
Stock GM MLS 6.0L HG's approx 10.8:1 compression ratio
235/242 .621/.624 114+3LSA Comp LSL Lobes
1.75" LT's w/ 3" collectors
Hooker catback
I'm hoping with my fresh 4L60E/4000 stall combo and a better tune that I'll net something a little higher!
