Boost spike help.
http://rides.webshots.com/album/60796136stzCYb?start=96
On the dyno the spike would happen i believe when it down shifts.
At the track the spike boost happens when it shifts into 2nd gear. It feels like the car relaunches when it shifts into 2nd gear.
The spike boost jumps up to about 14-15lbs.
The motor is completly stock, only mod is the sts turbo.
any ideas why the spike?
thanks
