View Full Version : Installed HPP3
06-28-2003, 01:22 AM
I put installed my programmer on my truck tonight. It made a difference in power and I am impressed with everything but shift firmness. it shifts harder with tow/haul on. My friends has a 01 with a hpp3 and he chirps 2nd gear with 315/75's. Is there a way to make it shift harder? I raised it +5 for the 1-2 and with the firm shift turned on it still shifts slow.

he has a lil more poop to bark with... a 2001 vs 1999
you might wanna try
make sure the speedo is calibrated correctly
shift firmness yes
try it without the engine tuning too.. may be over advancing the timing
killing the torque... secondly, your torque management is ripping
22-40° of timing retard on shifts.

I tried that and it feels stock. I guess its just going to be as firm as it is now.

What rear end gearing you running?
What is your friend running?
That will make a huge difference.
Also, your low end torque may be less since you are running straights.

we both have 3:73's and he has flows
My page is down right now (ISP is doing maintenance). Click it tomorrow and check out my settings.
I have a 2000 5.3l 3.73 truck. I can't chirp 2nd though, Torque Management won't let it happen and HPP3 cannot remove that :read:
