senario: I am coasting at 30mph to 35mph my rpms are around 2k with foot off the pedal. Then trafic starts to move so I push the pedal from a lite or even 1/2 throttle and rpms go up for a second then it upshifts bringing rpms down to below 2k. This causes some extream bogging. Kinda like starting a manual in 2nd from a stop. It seems to do this if the outside temp is above 70 degrees.

06 auto gt, C&L cai, Brenspeed, bama, tillmans and even stock tune does this.

Any ideas?

Update: After new fuel filter I now have a better idea of whats going on here. This only happens when I press on the gas slightly and not 1/2 throttle. Its still annoying though.

Say I am going 35 mph and traffic starts moving to 40mph. You dont want to smash the pedal to go an extra 5 mph so I just slightly hit the gas and it upshifts way too soon. To correct this I almost have to WOT it for it to downshift so I can accelerate
