1.6sec and 350rpm later = 8.8psi

[M3TurboCa]

Here was a little driving I did the other day.

I was driving around 3000rpm in 5th gear and wot and logged it with my LM1.

By the time the I looked on my boost gauge it showed 10psi the rpm on the tach was around 3350rpm.
The LM1 shows 8.8 psi.

If you look on my LM1 graph there are a few rpm blips the 3730 rpm is around 3350rpm.

This was without my greddy profec B boost controller being on. I have a 10psi wastegate spring. With the cold air and the boost controller on boost builds too fast and feels scary.

During the winter I usually run with the controller off so I get a sort of a gradual build but boost still comes on hard and fast.

Since I had my new blow off valve installed Oct 04, the Greddy Type R I can build boost much fast and harder than before.

Hey Mark,

As for the blips, I seem to get them from time to time also. Never sure what they meant. Sometimes I thought maybe they were tire slip, but not sure.
