I recently got this kit because it is cheaper and i also got the GM modified upshift valve kit(it lets you go to 4th at wide open throttle) my first question is--- is the mtv ushift valve(b&m name) and themodified upshift valve the same thing?.Also while reading the directions i noticed that they want me to remove the spring next to the mtv upshift valve (that does not sound too safe) iwas wondering if anybody got an alternative?

THANK YOU FOR YOUR TIME!!!
