vtec controller settings?

Hi i have a APEXI V-AFC II vtec controller and im new with them and dont know what the settings should be at. right now the

WIDE LVT is set at 2500 +0 it can be set from 1000-6500

WIDE HVT can be set from 3500-9000

NARR LVT is set at 1000 +0 can be set from 1000-6500

NARR HVT can be set from 3500-9000

V/T L --> H can be set from 3100 rpm - 7000 rpm

V/T H --> L can be set from 3000 rpm - 6900 rpm

V/T UNMT is set Hi<<L +0% can be set from -50% - +50%

V/T UNMT is set Lo<<H +0% can be set from -50% - +50%

TH - POINT NARR. is set at 10% and WIDE is set at 50% the NARR. can be set from 0% - 49% and the WIDE can be set 15% - 99%

Okay my car is a 5 speed 90 acura integra with a b16a dohc vtec all the motor really has is a cold air intake header and full exaust. if anyone could help me with these settings it would be amazing because the vtec isnt hitting like it should and its not pulling that hard either. thank you!

    YOU HAVE MAYBE 170 HP... IT SHOULD NOT BE PULLING...

    APEXI V-AFC II vtec controller IS FOR HIGHLY MODIFIED CARS NOT A B16 WITH 2 GRAND IN IT.

    I SUGGEST YOU UPGRADE YOUR FUEL DELIVERY SYSTEM IE BIGGER/BETTER VALVES, FUEL PUMP, THROTTLE...AND CAMS

    YOU SHOULD HAVE PUT 5000 MORE INTO YOUR ENGINE BEFORE YOU BOUGHT THAT PIECE.
