boost spike and high boost on stock ms6

[b20eg6]

Im having some boost spikes whenever i put my foot down it spikes to 17 for a second then drops to 14 and stays there till i let off. Tried 2 diffrent boist guages both read the saame. Any reason y its spiking and y im running 2 pounds more then i should be? Thx

17 is not bad .. I spiked to 25.. then again mines got all the boltons besides the top DP piece. You can reset your ecu and drive it around for a few hundread miles then see if it does it.

Mine adjusted itself after awhile I hit 17-18 psi no more spikes above that

Ecu has been reset and still spikes so it normal for the speed to do that?

Your gonna have to drive it around a while.. Let it adapt.. It should correct itself.. Also what gauge are you using

check for boost leaks, any loose clamps, any/all hoses, connections, etc. Your waste gate might be mulfunctioning and lagging just enough for a spike. Check oil levels. Check the connectors to BCS.
If your car is completely stock and it behaves differently from what it used to, there is some kind of mechanical issue.
