I Love it. But, did I do something wrong ? Ever since I did the Boost p[art I get a whistling sound coming from the engine compartment. When I take off from a stop. I used the bango bolt and I checked for leaks but at ilde or wife holding throttle to 2000 rpm there is not enough boost. Any ideas ?

When I positioned the box under the dash, I accidently knocked off the rubber hose adapter and it was sucking air, which, made a loud sound. Also, one time, it was making a really wierd sound and I couldn't find anything wrong so I took it for a ride and wound up the engine, a bit and all of a sudden the noise went away and has never come back.

It is a rushing noise that gets louded as the boost goes up. I checked with a soap and water solution for leaks and can not find any.

I had the same problem.



First, check that the hard plastic hoses are FULLY seated in their various couplings. Then use a hose clamp on the soft rubber hose connections. Mine would not leak and make a hiss until over 10 psi boost. You can only get maybe 3 to 7 psi boost when standing still. If you don't have a hose clamp, try the 1/16" zip tie. Two zip ties fixed mine. Then I bought a hose clamp and put that on. The zip ties just confirmed my diagnosis.
