running very lean.
I didn't have any jets with me to correct it at that time.
I will be making another trip to the dyno this spring hoping for some better numbers.
Thanks

Your engine is making a BUNCH more than mine, as the numbers I posted for my engine were from engine dyno pulls.
Running through a single (non-PYPES) crossflow muffler mine only made 299 CBHP @ 5300 on a Mustang chassis dyno.

We couldn't get a decent torque number on mine on the chassis dyno runs.
I didn't have an O2 sensor hooked up for my chassis dyno runs, so I have no idea if it was running lean, fat or what, LOL!
