Default post mods dyno...sucked...

car did 365 rwhp stock. same dyno, similar temp, more humidity today. mods are k&n and iss forged track sys. car did 365 rwhp...again.

so after 2k in mods i picked up 0 rwhp. awesome.

my z06 also read 25 lower than a mustang dyno which doesn't seem right. i've never heard of a mustang being higher, always lower than dynojet.

i'd like to think the dyno was f'd, but i don't know.

Dyno was defiantly off. You should be in the 375+ range.

Maybe the K&N negated any gain from the exhaust. hehe j/k well kinda. I would go back again with the stock intake and see how you do. I'm also assuming your dyno runs are corrected SAE?

I've never reset my ECU and the car has always learned the mod and adjusted accordingly with positive gains.

545 on a mustang dyno. 521 today on the dynojet. i'd like to say the dyno was screwy but another z06 owner did 743 and 750 on the mustang i was on before so i don't know.

also, i need 750 rwhp now

i assumed the car would learn eventually and that's why i never did the reset. i went ahead and did it tonight anyway. don't plan on taking it back to the dyno anytime soon though as it costs too much here.

No mustang is lower than a dyno jet period. If it was a dyno dynamics then maybe. The operator strapped it down too tight or something
