Got an Osiris Dyno Tune @ Infineon Raceway in Sonoma, CA for $650 by WORKS today and this is the number I got. Does it look right to you guys?

GAINED + 13.6 HP / +8.1 TQ
254.8 WHP
241.9 Torque

MOD LIST:
HKS HI POWER
RESONATED TEST PIPE
5/16 MOTORDYNE SPACER
MREV2
Z-TUBE
K&N DROP IN FILTER

 

Yes, that is about right. The vq35 doesnt leave a huge amount of room for increasing horsepower unless you do a complete NA build. Then you will be lucky to top 300+ whp. I think your numbers are about right, considering I have everything that you without a tune making 246 whp.

 

yes. usually you'll gain anywhere btwn 10-20 in hp and torque. osiris will only do so much. it really depends on your tuner. some tuners are better than others. I've seen as little as 3hp gain which i think is pretty freaking terrible but looks like you did good.

 

nice to know =)

 

one of the member with k&n drop in, ztube, HFCs, catback, 3/8'' spacer and mrev2 with a osiris tune and he dynoed 285.5whp and 277 wtq, which makes my numbers look like shiet*... should I get a retuned?

 

Depends on where the Dyno was done. There is some variance in the dyno numbers and others almost always come back "high". Check with some of the other CA people as I think they know which ones are accurate and which aren't.

 

you cant compare what you dyno to what someone else did. there are too many variables the biggest being what kind of dynamometer he was using compared to yours (mustang dyno, dynojet, dynapack, dyno dynamics). you are comparing apples to oranges. the only way would be to get dynoed on the same day one right behind the other.

 

Ohh i see, i was just wondering though. Since my ECU got Osiris flash, does this mean I can go to any tuner to get re-tune without paying for Osiris flash again or I can only visit the same tuner shop?
