Boost gauge possibly just saying...First off it could be Ure. S.c bypass valve port for the butterfly tests the issue. Check to see if there's a spot where the door gets stuck..... You will be able to notice it.... If thats good. Check Ure Injectors seals. If that's good check Ure Injectors insulation seals. If that's good do a compression test leak down test... And you'll find it.. Check for a boost leak..

 

put a mechanical guage on the car

 

Ok so I just think ive found the problem.... Hopped in the car to go get lunch. I rev'd it up a few times and the boost gauge didn't move at all from -20 vac. I started driving and it still didnt move... So I smacked the gauge and it jumped up to 0psi and crept to like 2psi. I caught a red light and while I was Idling it was reading -10...... I tapped the throttle and it dropped to -20... Im thinking its the gauge? Im going to go with a Mech. one if this is bad. Any further suggestions on the problem or a recommended mech. gauge to go with?

 

I put a mechanical Boost gauge in the car..... And Now Im getting the exact boost I should be getting right at 16-17psi. So watch the Junkie stock electronic boost gauges they can turn a $60/30min fix into one big headache! Thanks for the possible solutions guys! The only trouble im having now is getting the damn thing to light up! I tried the Ign. and the dimmer. I tested the Bulb before I installed the gauge and it worked fine!

 

That sucks. Least it was only something small. I hate when things like that happen, or fuses blow, and you think the whole system is screwed.
