I have a hx52 and it barks bad between 3-4 especially towing 5k lbs like today. Had a quick merge and didnt adjust the POT to delay the 3-4 intime and it barked bad for about 3 seconds from 46+psi down to 10....
I was praying so hard it didnt snap the shaft I almost drove into the ditch on i95.
Im going to wire my pot into the ground circut of the tps instead of replacing the tps. This way I can delay the shift depending on throttle position. This way when you have your foot on the radiator merging or passing in 3rd (worse when towing) it doesnt shift and lockup dropping 800rpm in a split second (like my ats
VB does) causing an arse puckering noise you never want to hear 1100 miles from home
I will take a vid of mine towing tomorrow nothing to be proud of, 3-5psi @ 1000* 4-5k lbs problem is with 35s, 3.55s in lock up puts me at about 1650rpm at 70mph. Now try keeping the egt under 1200 towing at that rpm/speed through the mountains with next to no boost :doh
