My 2011 GSR has the following performance mods:

$175 - Test Pipe (MAPerformance)
$335 - K&N Typhoon Air Intake with included UICP
$225 - Eibach Pro springs (not sure if this would have an effect on these numbers)
$600+320 Custom MAPerformance tune with Cobb AP (on 93 Octane)
$60 DIY Tranny fluid/transfer/diff change with Redline cocktail/fluids (not sure this matters, but since I did this, wanted full disclosure)

I ran this on a dyno day with the Cobb stage 2 stock airbox OTS map, and it hit 300hp, but had terrible boost drop and AFR was very rich. So I brought it in and got it tuned. Here is the graph (they printed it, didnt send electronic, sorry about terrible quality).

What do you think, good numbers for all of $1750? I guess I could have saved money and went a different route other than Cobb AP, would recommend a different route to others.

 

Tried to combine the images to see where the change occurred, looks to be only 5.5k and on:

 

Hey, nice power!

 

I think those are good numbers for the mods you have. How does the car feel with the MAP tune?

 

 

The car feels great, I have yet to take her to the track to compare. I did 3 (for fun) autoX days prior, one before the springs, two after the springs, both with the Cobb Stage 2 OTS and Intake/test pipe. Car felt great those runs, but they were both 2nd gear only. I can say I tried a 2nd gear pull on the streets and it feels quicker through the gear, so I am excited to try her on the track. I am planning to run this coming Sunday at the PDX event and then I will know better how she is taking to the new tune.

 

Thats awesome power for the money! Not many cars can match that gain per dollar believe me.

 

Thanks, you made my choice for an AP dyno tune between MAP and DB a lot easier.
