Osiris tuned today-results
There is a mixed message in here I guess... OP- I overlooked that you're an early MT... before they went to the rev-up. 250 starts to look a bit more reasonable but it still seems low for that kind of hub mounted dyno. I suspect it has something to do with the stock cats but others may be wondering about the tuner.
I think as someone mentions above instead of d1ck measuring guys were just hinting that there was more to be had and if you're going to spend your 600 bucks for a tune that you get your money's worth.
I'm glad you're happy with it but I think many will agree that some free(er) flowing HFCs would have definitely sweetened the deal for you. Maybe for phase 2?

Seems okay to me. I really don't like the dyno chart the shop provided you with. For the money you spent it would have made a lot more sense to buy and diy a plenum spacer before ($150) tuning. Oh well.

not bad...and your running a CAI??
by chance did your tuner increase timing?? and you're driving a sedan, correct?
I have a sedan also (M35) and dyno'd my car on a dynapack...was pleasantly surprised with results...then added more mods along the way
NEAR STOCK (K&N drop in, stock mufflers w/xpipe and 2.25" piping from cats) =

(5/16 MD plenum spacer, MD MREV2, MD Isothermal gasket, K&N drop in, z tube, G35 Ypipe, Megan exhaust 2.5"mid pipes & axle backs, NGK spark plugs)
whp: 281 @ 6408
Tq: 255 @ 4693

...I think if you feel the difference after your tune, then you're good......

I had Osiris standard tune installed and tuned today at Advanced Powerhouse in Toronto
Modifications:
Exhaust-Y pipe, Tanabe piping with Skunk Megapower muffler
Apex'i Intake in custom cold air box.91 octane gas
Base line 236hp/239 tg,
Tuned 250hp/242tq
Dynapack dyno.
160K km on the clock. I guess 250 whp is not that difficult after all.

All that said, still decent gains from a tune. Lots of good posts on this shop here, including from previous Osiris tunes (and I think they're they only one in Ontario... maybe even Canada).
I'm going to try Advance Powerhouse for a tune in the spring, so I'm in for other comments or reviews.
I can't locate the sheet which displays the run I did with the BERKs installed...it's actually very frustrating since I know I put in the same place as the others
anyways, here is the pull prior to the Berks added(same as other post to different thread), as well as a pull done to see my TQ - enjoy...
