Well... ... ..... I pulled a 4000# trailer today:
I am idling at 1000 rpm, and WAY down on power!!!!!
I mean, when it locks into OD at 50 mph in 4th, it falls on its face! My egts _used to_ climb to 1250* at this low rpm under full load, now I can not make the egts even reach 1000, and boost is down to 15 psi or so, and just climbs up with engine rpm.
I talked to peirs today, and they are sending me a #10 plate. They told me the #8 plate is not the best choice for the 3000 rpm with a auto.
Also, as a side note, they asked at what rpm my fuel began to drop off, but if I put my trans in "OD off" (third gear) the TRANSMISSION will just let go at over 2500 rpm when floored. I mean I saw 4000 rpm for a instant and it jerk like hell!
I will be installing a new DTT trans next week.
I think I will leave it alone until I get the trans installed anyway. That way I can "tune" it in its final drive line set up. I will installed the #10 plate, then loosen off on the springs, then adjust the rocker. My back is gonna love this!
