So I got my car dyno'ed today. It ended up putting down 332hp and 340tq on a mustang dyno. It ran around a 12.5 afr with 30 degrees of spark. Next time I go i'm going to try 12.8:1 and a few more degrees. I was expecting slightly bigger numbers, was I asking too much?
A Mustang dyno typically records numbers 6-7% lower than a Dynojet. Therefore you could have got about 355rwhp and 365rwtq on a Dynojet which is very good for a 331. Unfortunately it looks like you're spinning away too much power at the tires 'cause with that amount of rwhp you should have been in the low 12's.

I'm thinking about alot tuning, It ran good last year but it still wasn't as drivable as stock. I'll post up a curve of my dyno too when I get a chance
