Negative.....on not needing a prop valve! I know you're not going to want to hear this, but you're headed for some seriuos braking control problems.
I'll bet a dime that at the moment, the rear brakes are not adjusted down far enough so that they are getting a bite. What you're running now, is basically front brakes doing 90% of the work. Might be okay under normal driving, but when you have to brake hard, especially on wet pavement you'll see what I mean. No...you don't want to see what I mean!!!
Adding the adjustable prop valve (Summit Racing SUM-G3905 $36.)is going to prevent you from having a VERY unpleasant experience down the road. On both my trucks I have the valve cranked down fully and backed off 2 turns. I've got mine mounted so I can adjust them from inside the cab, down at my right heel. With all the varying road temps and rain we see down here, I've been able to fine tune my bias to compensate and can safely navigate in heavy traffic. Pic in Webshots albums.
Obviously it's your call.....but I'd hate to see you have to eat up half a Camry or a Lexus to get the message.
