Question Need help diagnosing several electrical problems probably connected...

1. Boost that starts to rise and fall systematically (no ordinary hunting) above .6 bar only at mid-throttle. When it fluctuates the gauge looks like a metronome. If I increase the throttle or go WOT, it stops and finds its target without issue. This is getting worse and resets don't do anything.

2. My laser detector is going off when I got to WOT--with the throttle about half to three quarters open (consistantly--I thought for a while cops with laser guns sat in the trees, Planet of the Apes??)

3. My alarm has been acting strange--both remotes are malefunctioning simultaneously, one is no caput.

4. This all started within a month of me completing "the grounding mod," which changed the way the car ran so dramatically that the car called foir an adjustment in custom mapping, which Trey Cobb thought was odd.

Where would I start to look for some type of grounding problem or source of interference?

Should I remove the grounding mod? It is simply three wires from the two grounding points on the intake manifold and the one grounding poin in the middle of the firwall behind the intercooler.

Thanks,

Whit

1. wastegate?
2. Electrical interference between the engine and detector
3. check the antenna for the alarm
4. try removing it, what harm could it do (other than 1/2hp)

Either that or aliens are laughing at you.

I removed the grounding mod, did a Vishnu reset--the problem with the boost is still present. The detector is not going off now. The aliens are laughing...
