I have a 2011 GSR my plans are to keep it mostly stock. I am about to order a CP-E catback exhaust, Cobb turbo inlet Pipe, and the Works panel filter, And Cobb APMy questions are according to Cobb's website they still only have beta maps for a 2011? Also after reading about the AP I noticed they say to run the stock air filter with a stage 1 tune.It seems the more reading on the AP I do the more confused I get, it seems some people are running 2010 maps some are running the beta maps so I am not really sure what I want to do now.These are going to be the only engine type mods I am going to do and I just want to make sure the AP stage 1 map is going to work with these mods.Sorry cause I am sure this has been covered before but I am not finding the answer and searching for it has become overwhelming.

 

I had an AP for my 11' running the stage 1 beta maps and it was mediocore on an otherwise stock car. I never tried the 2010 maps because I'm selling the AP to get an OpenECU tune, however, if you do run AP stage 1 with those mods I would keep a good eye on your boost levels because I noticed stage 1 spiking to 28+ psi on my car right before I uninstalled it to sell.

If boost checks out and doesn't spike on your car and you get little to no knock sum you would be ok for a bit, but I would highly recommend getting a pro-tune, not only for reliability but for more power
