jerky WOT

[OMGTruk]

i'm not sure if this is trans or tuning related but at WOT it feels like it pulls hard for 1500 rpm then lets off the gas then pulls again for another 500-1000 and does it again, This happens very quickly and clears up quickly but its still odd. It will do this about 75% of the time I get on it. Does it from a dead stop or from a 20 roll or a 40 roll, not from an 80 roll in 3rd though.

mods are cold air kit and magnaflow catback

otherwise stock 5.3 w/ AWD

if you have torque and an odb2 adapter, monitor knock retard, see if its pulling timing
