Default boost leak? Boost leak. Boost leak!

So, I not only peak at 25 and drop down to 10 afterwards, but I pendulum all the way between -25 and +25. I was crusing down the highway tonight at 70mph and my boost was sitting squarely at zero. Hitting the accelerator would send it up to about +15 max, but as soon as I let off the gas, it drops down into the negatives--and this is at speed.

One thing that may be leaking, is the compression fitting on the back of the gauge. I only tightened it finger tight. I'll check that and get back witchall!

Default It's normal to go...>

to -25hg off throttle. Max boost will vary depending on the car/tune. 25 is too much though...Dial it down a little and tighten that fitting!
