Morning everyone. Here's the scoop:
2002 GTP Sedan
New build mods include:
3" C-less DP
P-LOG
180 T-stat
Ported outlet/inlet Gen3
Ported Stage 2 ZZP Throttle Body
ZZP 9" open cone intake
1.8 Yella Terra Roller Rockers
New stock heat range plugs
3.3 Modular Pulley
60# Deka injectors
I just got the top end put back together and have been doing some tuning and scanning with HP-Tuners.. My issue:
Under part throttle ONLY, I get HUGE KR spikes.. this mainly happens when cruising in 4th gear and then gradually getting on the throttle. See snapshot of log screen below. Note that it does not happen when I really get on the throttle from a dig or off the line, etc. I have been up to 90%+ throttle on side streets from a standstill boosting up to 10 psi thus far with minimal to no KR (less than 1* or so).
I have currently set PE mode to come in around 32% throttle across the board. As you can see above, I am not even in boost yet and am seeing 5* of KR at 24% throttle....
Anyone know what I am should be doing next? Should I make PE come in even sooner to try and add fuel where I am seeing this KR? (PE mode at 20% TPS sounds crazy to me.. but not positive)
is the 3.3" pulley too much for my current mods?? (if it is, I will do E85 on my next tank)
let the thoughts/suggestions start flowing please!
