    did a slow roll to WOT with 19* of timing with the 3.3" pulley. my ngk afx wb i just installed showed a steady 11.3-11.5 and i only get blips of KR, but mainly i get upwards of 5* at the shfits, but at the 2-3 shift. it'll drop to zero the longer i stay in throttle. the devils own controller is set to turn on at 4.5psi and the max psi knob is set at 7.5psi. also i had to increase my commanded pe afr to 13.6 to see what my actual/dilaed afr would be. when i had the commanded pe afr at 12.5 i was in the 10.2-10.5, but thats a different story. whats the table in the PT that i can lower the timing being pulled at the shifts again?. thanks again

    Do you already have torque management disabled?

    Go into the TM section. Then go into the spark retard vs. torque reduction table.


    If you don't want any TM at all just zero out that table. If you just want less TM then you would need to do that via the gear and rpm tables. And you would do so by reducing those numbers.

    yea under the spark table then tm theres a table called spark retard, and all of the percentage values are zeroed out.

    In that case you already have TM disabled. You may just need to do a timing tune.


    That Max psi knob.... is that when the alky is suppose to cut off? At 7.5 psi? If so that may be you're problem. Sounds like it is cutting off when you get into the higher boost/rpm ranges

    no, when it basically says that at 7.5psi to spray at full capacity.

    edit- i went ahead and lowered the TM under the tranny folder for the 2-3 upshift perf mode. see if it helps
