finally made it to dynotune Just got done with my dyno tune after waiting about a year to get everything tightened up. This is my 355 with ported heads and the GM846 cam, through LPPs,cat's and a Borla. Happy with the numbers and the car is so much more driveable and throttle response is a lot better. My original goal for this car was about 425-450 flywheel horsepower so I'd say I did pretty good against the goals. torque curve looks nice too.
Time to fix the A/C, too dang hot today in Chicago

Those #'s look pretty low to be honest. I made 375rwhp with that cam on heads that only flowed 240cfm. It also looks like you're getting valve float too which is hurting peak #'s. I shifted around 6500 and peak hp was around 6200 IIRC. I would expect at least 400-410rwhp with that cam on a 355 with ported/epoxied heads.

He is not using the donkey dong 847 - hence him actually making tq, and peaking much earlier
