All I can say is ...I'm still in shock. All I have is an 03 G35 6mt with injen cai, berks hfc and the motordyne 5/16 iso thermo. I'll let the dyno tell the story. (hint: gain 23 rwhp & 16rwtq ....from just the tune! the 244 rwhp baseline was with the mods)

 

wow! that's amazing and i have the same mods you have

 

that is pretty impressiev.

 

Nice I just had mine tuned on Tuesday!!! Was it on a mustang dyno or what?

 

^ The heading on the Dyno sheet clearly answers your question.

 

Those are good numbers, congrats!

 

The difference is astonishing. The car's power delivery seems silky smooth through out the rev range. DE's are known for being a bit harsh at times. Well the tune definately is a cure for that. The biggest (and most appreciated) difference is the 3rd to 4th gear transition. Anyone who has put in a lot of unofficial race time has to know what I'm getting at. Too many times, I have hit perfect shifts (gears 1 through 3) take and hold the lead on a said faster car. Then it happens, I shift to 4th and the car "gives up the ghost". People used to ask me "what happened? you had me worried for a minute then u let up"....WELL NOT ANYMORE !

 

Oh didnt see that thanks. I figured it was a Mustang...
I made 270 on a Dyna Pak...

 

wow

was your car running lean before the tune? did tuner supply an A/F chart?

i just added an OSIRIS tune and can really feel a diff in throttle response and upper rpm power but i don't think i gained as much as your dyno-tune.

do you have any OSIRIS logs to share / compare?

 

I'm sure he has the af ratios....He did say the car was running kind of crazy before tune...however it still made 247 whp peak on one of the dyno runs....the curve was all over the place though.
