Hey guys, looking for some help. Im doing a whipple for the first time and having some hick ups. For some reason, when slowly getting more load, the truck will go super lean, truck will loose lots of power, timing goes way up and cyl air goes from ~.61g to ~.35g at 30% throttle. Map also shows it going from ~75 kpa to ~65 kpa. You can see it multiple times in the log at 1:02, 1:10 and 1:46. I am trying to use only SD and not MAF. Also, Im in Denver so my kpa when it was an NA motor was 82 kpa and .75 cyl air mass at WOT.
Truck setup:
6.2 swap with PRC heads
BTR stage 3 blower cam
Whipple 2.9 ~10 psi kit
1 7/8 headers
3 bar map sensor
4l80
ID 1050x injectors
92mm throttle body
11:1 afr to start with
0 degrees timing to start out safe at WOT
Thanks!
