Good question Smokey. I have often wondered that too. I think a guy would be alright to run the bigger RPM spring in the VE pump as long as he had the high idle set to 2900-3000 RPM. But, if you can put a larger spring kit and not mess with the high idle on the P Pump. Then that blows that theory clean out the door. ???

 

;D it is a shame you guys are so far away from soddy- daisy , tenn. i believe just the low end throttle response would convince you the spring is worth it. ps dont want anyone to hurt their truck ,but 3 ? years of the spring hasnt hurt mine. about 30k mi.
