  1. Thanks for the responses.

    Apparently the system loses vacuum at high throttle settings, and can not keep the throttle setting. By blipping the throttle ( factory cure) more vacuum is created , and the cruise will resume it setting. It is a pain to keep blipping the throttle on a long trip. Turbo Volvo's use a vacuum pump to maintain the vacuum for cruise and other functions. see http://www.mwrench.com/barth/vacuum%20system/vacuum%20system.pdf

    We will see if this fixes this.

    Thanks

  2. Well I tested it for about 20 miles through rolling hills at 60 mph plus or minus. Worked OK on little hills but what I found was the cruise control could not give enough throttle on the steeper hills. Dropping out of cruise control and manually giving it the gas would bring me right back up to 60 mph plus. Might be OK using it in Kansas with no headwind. And as a note at 60 mph the engine is running at 3500 rpm.

    Hope that helps.
