i was a bit disappointed with my dyno last year (187 4th gear dynojet) and thought something might be jacked. ended up my header cat was pretty jacked up, i assume from continuing to track on a misfire code and some unspent fuel getting onto it.
i have a new tune this year and this header cat has been smashed out. i don't think it's changed anything else but a new overpipe/front pipe with a new high flow cat itself. on an awd dynojet i got something closer to what i was expecting, 195 (3rd gear) - unfortunately no torque or a/f at this dyno day.
as far as i can tell, this seems around the same as a stock AP1 s2k would do on a dynojet (195-200). last year OEM tune OEM 86s on 93 put down 175-177.
