Hi all, newbie here
l have a 2013 opb sedan with 1200 miles on the odo.
Bought the car with seven miles on the odo and had been driven the car under 4k rpm for the break-in period
Today, l've wanted to see how much boost the turbo is generating and did a couple of slightly less than pedal to the floor acceleration on the second gear. This is what I've observed and concerns me:
Between 4500-5200rpm: boost appeared to settle at 10lbs
Then the needle on the boost gauge fluttered wildly between 13-16lbs when the engine rpm was around 552-5800rpm
The car is bone stock and it's a limited pkg that was equipped with the SPT boost gauge, the STS and the SPT axle-backs
So, what gives? Thanks folks
