I just installed the Edge Pulse on my 99 Q. Cab 4x4 auto with 3:54 gears. I am running it on the lowest setting which is a 60hp gain. I pull my jeep and four-wheeler on a trailer frequently up some pretty good grades. The total weight of the trailer is no more than 6,000lbs. I am installing a BD pressure lock tomorrow for the lockup converter. Is this setup going to hold up? I don't want to roast the trans. I ran the box on the highest setting for the 2 mile ride home, and man does it run. It runs too good. I am sure alot of you guys are running a similar setup, any info would be appreciated. Thanks.
