Supercharged K20 bogging off launch control

Post by sicones »

Anyone have any idea why this Comptech supercharged K20A2 is bogging when launched off the 2 step. Attached is a datalog of the launch and calibration. Even with the launch control set to 6k it just falls completely on its face. On the street it should spin the tires violently.
Tune was made from: k20a2-rsx-650cc-jrsc-10-psi.kal
Timing and fuel is pretty conservative tuned on the street.

Specs:
AEM wideband is connected to analog input 0.
K20A2 in EK
drag radials on street
pump 93
hytech rep swap headers, full 3" exhaust
Comptech s/c with the smallest pulley they make, apparently should build 11-12lbs
3" cold air intake routed all the way to the front bumper, ebay air filter
RC650 injectors
