Different Boost spikes
 

I was just doing a fun run today that lasted about 3 hours with a few stops for some resting but anyways, my car is completely stock with no tune and I was seeing spikes around 17 and 18 psi in a second gear pull. I know the stock psi setting is 15 and I would normally only see 15 and no more. Also in first gear I was seeing around 14 psi. In second and third, I started to see 17 and 18 towards the end of the run. I was never really hard on it for this long of a time before but I still get on it every once in a while. Is this normal, bad, good, or just Ssweet!! Has anyone else ever noticed this.

its normal. it should go to 15lbs and then spike up to 17 and slowly drop back off.
