Please Critique my Dyno Graph
Please Critique my Dyno Graph Here is my dyno graph that I fianlly got. I'm not sure what to think about it. It looks okay to me. I kinda wanted the torque to be little flatter, is it okay? And it kinda goes up fast, flattens out, then goes up more, is this normal? I am looking for concerns, problems that can be determined from the graph and then fixed.
Numbers:
366.83 rwhp @ 5700 rpm
373.69 rwtq @ 4300 rpm
Engine Mods:
- TSP Smoked Clear Lid
- K&N Air Filter
- Jantzer Ported Throttle Body
- Taylor '409' Pro Race Wires
- TB Coolant Bypass
- Thunder Racing 224/224 114 LSA Cam
- Thunder Racing Chrome-Moly Hardened Pushrods
- Comp 918 Springs
- Rollermaster Double Roller Timing Set
- Ported LS6 Oil Pump
- NGK TR55 Spark Plugs
- Ported MAF Housing Ends
- !EGR
- MAC Mid-length Headers, Jet-Hot Coated
- 3" True Duals
- Dynomax 12" Bullet Mufflers
- X-pipe
- Maganflow 4x9 Oval Mufflers
- Dyno Tuning
- Hypertech 160 Degree Thermostat
The A/F spiked at the end from the gauge falling out of the exhaust at the end.

Are those numbers after PCM tuning? Generally, a low plateau in the torque can be cured with some more fine tuning.
It seems like the cam is peaking a little early for a TR224 114, but the power looks about right for your mods.
I noticed also that with my true duals, I get a "stepped" look to my torque curve that wasn't there with the y-pipe setup. My stock cam, 2.5" Magnaflow duals torque curve looks very similar to yours...except only around 340 peak torque.
