Getting ready for Hptune and was looking to upgrade to 3 bar map sensors as stated in research on this site. When checking my 2009 TC looks as if it has them. When purchasing car I was told it is fully stock...it has paper filter and I have found no mods.

Was immediate upgrade to GM stage 1 an option? This is the correct sensor?



Thanks for the help

 

Does that also mean since learn down is removed I can install my intake pretune with no issues?

 

How much boost is your car running? You might have a gms1 tune

 

gets to 20psi...stock is only at 14?

 

Yeah you have the gms1 tune then 14-15psi is stock

 

Those look like GMS1 sensors to me. Stock sensors are all black.

Your PSI would confirm that.

You can run some intakes like K&N with GMS1.
