my 06 doesnt seem to have much power below 1800 rpm upper end, is great is there something I can do to get the power to come on around 1200 I have a smarty and Im running on three I end up running between 2000 and 3000 all the time or the truck drives like a pig I have checked for boost leaks found nothing. Is there any thing else I can do or do I just have to live with it? i dynoed it today 368 668

Try and download a wild tq man software, your clutch wont like it but it will run better on the better bottom end.

Shouldn't it have been higher on both the HP & TQ when you dynoed it? What's your boost #'s looking like?

My CFM+ airhorn really helped the bottom end on my truck....

Actually, for Smarty level three and nothing else... that is about right.

pressure box.

The quad xzt w/ pressure only tune has good bottom end.

Whatever it takes to get Boost pressure up over 10psi and climbing rapidly at those low rpms - you need to note the Boost levels soon as you nail the loud pedal, compare how the truck responds at 0, 5, 10, 15, 20, etc psi, as rpm climbs - you'll quickly note that it is Boost pressure that makes power - early Boost is early power - not as easy with the manual trans trucks as with the auto trucks, as they can stage for power against the torque convertor load - you don't have that option unless you hit the brakes and slip the clutch till Boost gets up where you want it, then side-slip the clutch and brake and go - kinda hard to do with only two feet and three pedals - racers do it with an electric brake lock - step hard on the brakes, push the shifter-mounted switch which locks the brakes hard-on, hold it till you're well staged, then release the switch - very hard on clutches, btw

Sorry. I was under the impression he had the Smarty turned all the way up for the dyno.

my clutch already doesnt like me so I havent ran it on the higher settings but turbo just doesnt seem to spool until the rpms are up there I was thinking of changing the intake and a few things like that to see if that helps.
