boost guage ??

[smokenstroker99]

when i get around 15 pounds or more on my boost guage the needle starts to wiggle and you cant tell exactly how much its pushing. i checked the tubing for kinks and didnt find any. is this a boost leak? faulty guage or what. they are autometers. any insight is apprecianted

hmmm...weird..mine dont do that..only time ive seen this is well faulty line OR you have turbo shudder..it goes like cha cha cha cha cha as you lightly push the fuel into the engine..

If you have the line "T" (teed) into the map sensor line or into the intake spider it can cause gauge flutter. Put a 90* fitting on the "T" and then install your boost line into it. It should go away or at least make it better.

thanks for the info guys. i do not have any shudder. so i will have to try the 90*. thanks again
