Hi, i have a 91 z28 with a 4L60 and the rear end was swapped out from the factory 2.73 to a 3.73. i installed a sgi-5 box and got it bang on to read the right speed while driving. at idle it bounces a bit but not while in drive. would the box affect the cruise from working? i cant figure it out. i got vaccum and all the hoses are good with no leaks. i changed the brake switch and my next step i am thinking would be the servo but before i spend any more trying to get it working i just wanted to know if the cruise works forsure with using this box?
