A little frustrated right about now. On a 3.5" with a 3" DP w/ cat, Powerlog, ZZP rear Powerlog, 104's gapped a .055", 180 Themo, 4" Intake, and an Overkill tune, I'm seeing varying degrees of KR. A few instances:
-WOT pull with the car fully warmed up, not really heatsoaked, I'll see 4-6 degrees of KR.
-Climbing a hill, around 2500 rpms, as soon as the car hits 4th gear it will start and bounce around ranging between 0.5-3.5 degrees. This is when the car is still not making any boost yet.
-On the highway doing 65-70 mph, in 4th with the converter locked, if I give it a slight more throttle to accelerate it starts doing the same thing as above, kind of bouncing around between 0.5 degrees and 4 degees. Keep in mind the car still doesn't downshift, and I'm still not making boost. I floored it at one point on the highway after driving for 30-40 minutes and the KR spiked as high as 8.5 degrees.
I'm guessing I've got a factory knock box that's always going to require maximal mods to run any smaller of a pulley?
