My engine blew while back and has been rebuilt. Now I'm working through little bugs and such and just recently I got it dyno'd since my first Dyno was several years ago on stock setup, now since rebuild , I decided to dyno it again. My dyno came back 14whp lower than stock... I assumed it was low on power. So I did comp test, 160ish across the board, max boost is 15psi with boost bypass mod, otherwise 13ish is as high as I can get it to go. Anyway I'm working with another tuner to check tune and see if that's the issue or partly anyway. But is there a way to test / diagnose the m62 itself? Im Wondering if there's somethinig wrong with it efficiency wise.. It's not noisy or anything.

Thanks again

 

bypass solenoid not working? What color is your cobalt? trying to find a guy known as blown4banger :p

 

Post your mods, and was it the same dyno?

 

Mods should be in my sig. And yes same dyno , around same time of year just several years later.. But if u can't see my sig for some reason here are my mods.

SRT.. Yea it's not working all the time, occasionally limits boost to 9-10psi . And I don't know many peeps locally, spoken to a few and had Chris (SCcobaltSS ) do the rebuild and original tune.
