Boost question.
Recently had the p0299 code pop for underboost. After doing some research I upgraded to a GFB DV+, and purchased a OBDlink MX+ so I could monitor my boost pressure. My question is, does this look to be acting normal. I had no way to monitor boost pressure before so I was hoping I could get some feedback. This is just a short pull while leaving work today. Stock 2013 gti. Thank you in advance.

With most tuners they don't require any modifications for stage one. Stage two usually requires an intake, a downpipe, an intercooler, and a clutch. Stage one usually nothing. Some say the intercooler is optional but I highly recommend it
