I just noticed the different AFR's on page 1. I read through the thread, but how does the timing look?

 

Timing is the same, I dont need to alter my timing maps on stock turbo cars.

The 2 dyno sheets on page 1 are an MR and GSR respectively. I dont tune the 2 the same relative to each other just relative to other years. As it is I am pretty sure the WB was taking a dump on the GSR as I dont leave them that lean for the street.

I've been watching this thread since page 1 after buying my 2012 GSR, and I figured I should post the results of my tune to add to the info pool. Tuned yesterday at STM (Mustang Dyno):

Before (ETS UICP, K&N drop-in) : 251hp/252tq
After (Installed a Hallman Pro MBC): 301hp/299tq

Picked up 50/47, and I had specifically asked that the tune wasn't aggressive. Emery did a fantastic job, car drives like it should have from the factory. Many thanks to all the guys at STM! By the way the car was manufactured in October 2011, and had 6400 miles at the time of the tune.

 

Doesn't mean a thing until I revisit the same dyno I baselined on last November when I was stock, however.

I have a late release 11. My VIN says 2011, but it's September 2011. VD showed 315whp with all the mods in my sig and 11* timing up top at redline on 91oct. It was stupidly hot and more humid than normal while we were road tuning. (it was 97*F at 11pm and humid enough to smell the grass....in Arizona :-\ )

Anyhow, I'm planning on visiting the same dyno I baselined on last November this Oct or Nov. I recorded exact weather conditions when I dyno'd last year too. So, I should be able to establish a true measure. I do have the impression that my late 2011 might be like these 2012s.

 

Hey John,

Did GSC get a change to check the cams? I'm still really curious to know if that was the issue. Thanks

 

I think Greg only ever got the 2012 cams I sent in, I dont think he has gotten any of the 2008-2011 cams to test against. I am working on getting some so he can do the comparison.

I have my stock 08 cams on a shelf in my garage....

Just bought a 12 MG GSR today and I'd have to say it impressed me with how responsive and powerful the stock tune was.

The 08 was a slug compared to this car. More than just a slight difference I'd say. It feels like the tune is much better and the exhaust seems a bit louder on mine.

I got it brand spanking new with only the few test miles as it was selected to be tested by Mitsu and I have the post-test checklist where it passed with flying colors. I have only driven the poor stock 08 tune and this 12 however so I can't speak for the other years. Keep us posted

 

The exhaust changed in 2011, since the note has been different.

 

Can we borrow them for the cam spec test at GSC? If so, I can arrange to have them shipped to him no charge for you.

Thanks

Aaron

 

Set it up, I'll ship them no problem! Maybe have Greg PM me a RMA number or something so they don't get lost?

 

PM sent

 

I'm actually a bit stumped after a tune I had this past monday with English. I pulled 301 with my 11 MR despite the fact I have (all ETS) 4 inch intercooler, licp, uicp, intake, catted test pipe and v2 exhaust.

I tuned last year at a dyno day with english and pulled 303 with nothing but the exhaust on it, but it was quite a bit colder out (it was in november).

In fact when I arrived my first pull was around 270 ish. 30 hp diff fromlast tune for almost 20 degrees in ambient temp difference sounds right, but the parts aren't equalling the expected power from both this post and the ETS posts I've seen. I'm at a loss where I'm going wrong with this car.

 

I know your car, I don't think you've gone wrong anywhere.

Did Aaron remember to turn off traction control

FYI, I had ETS UICP, LICP, 3.5" FMIC, HFC, Intake, Perrin Exhaust on my '08 MR. I was about 310whp. I was tuned conservative though.

Just checking, you were dyno'd on the same dyno? I know ER does runs in north end and their own in Camas.
