ok guys i did this swap for my friend here are the specs on the motor:

bored TB, skunk2 intake mani., short ram intake, anr intake mani gasket, ctr cams, itr header, 2.5" exhaust, high flow cat., converted to obd1, chipped p28 ecu running stock uberdata p30 map.

symptoms: hesitates at WOT all the way through higher rpm band. doesnt seem to be ignition related.

i checked the plugs and they looked quite white (lean). i was thinking maybe the hf fuel pump cant keep up with the demand of the b16 with a less restrictive intake setup? i used the obd0 fpr does if differ from the pressure of the obd1 fpr? any ideas? dizzy is new, plug wires have been checked for resistance, new plugs (what is the gap for b16?). any ideas?

 

what do you guys think?
