Dont need 4th on a dynojet to get the load right till past 650 somewhere, almost 700. It's all about the length of pull to judge if there is enough load (or turn the load control on if the DJ has it).
Whats the inertia weight on your dyno? Why wouldn't you always keep load control on? Just curious...
5000# is normally plenty of roller to maintain an 8-10 second pull on the dyno for 90% of our customers. With the way the dynojet load control is setup and variances in combos its not practical to set the curve up each time so it normally stays off. It really sees use on Diesels and 2wd cars only around here. If I have an Evo that makes more than 675 or so I dyno in 4th and maintain that same 8-10 second pull. I posted the difference between 3rd and 4th in my 3794 dyno thread awhile ago. Its amazing how far a little load goes, in this case just 4th gear for me.
