I had a chance to baseline my GSR at AZ Dynochip today on their Dynojet. Car is:
-- 2011 Evo X GSR, Wicked White
-- Completely OE (paper filter, Yoko A13's etc)
-- 4300ish miles on the car
--Crappy Arizona 91 octane (Chevron if anyone cares)
--Took a baseline to measure my mods down the road

Thanks for sharing man.

 

Wow that' really torquey.

 

no wonder stock runs under 4.5 0-60

 

That's not even that rich, very interesting. Thanks for putting up this info!

 

This is a pretty impressive baseline! Enjoy the car!

 

nice! and it's running rich 10.x afr. You have more room there.

 

264 seems like alot for stock car was it tuned or did u add more boost?

 

Nope, totally stock. Factory boost, factory tune.
It was 68F degrees, 28.9inHg barometric pressure, the chart posted is uncorrected, but it was a dynojet not a mustang, so it could seem high.

My tuner ran his 10' MR in august and got 254, so I thing this seems comparable for this dyno

 

Thank you for posting this!

 

The fuel gauge ran out at 10.0, you can see it was definitely in the 9's.
Let me guess, Prosport WB...?

 

good post and nice car!

 

the wide band stops reading where the line goes flat cause its to rich to read, so its richer than 10.XX up top

 

Yeah factory tune leaves quite a bit of room for some power.

The W/B was a Innovate LM2..I think. It belonged to the shop for their dyno. My tuner from my STi datalogged the runs.

First run had lots of heatsoak and 12counts of knock, but second run had 1 count.

Thanks for the comments everyone!
