Yo,
I just had installed a Prosport digital readout electronic boost gauge installed last week and after the car wash tonight the gauge does not read properly. I checked the electronic untit on the firewall and some water was in there on the unit. you think a little water messed it up??

Same thing happened to me.....I ordered a new sender (black box) from prosport and wrapped it up tight with all weather tape. The water, condensation will cause it to jump all over the place and not read correctly. You can order just the sender directly from prosport.

Water is messing up the signal, try to let it dry out. If that dont work, you will need to get a new sender.

omg who instaled it .....
euhhhh thats why other ppl dont touch my car they dont really bother by taping ends and setting it up properly , i would like to see pics of how it was plugged and where
