yes i've searched..last thread regarding p28 vs p72 dated back to 2003..inconclusive for me..

my car:
95civic lx b18c1 swap with i/h/e/ctr cams/ skunk2 IM pro/hondata IM gasket

i have 2 ecu
a chipped p28 and a jdm p72 obd1

p28 came with the swap that this guy did for me
picked up p72 obd1 from ebay

currently running on p72..i like it..easier start up..everything set at factory setting..

what i wanted to know is, which ecu is best to use for tuning?? since the p28 is already chipped, would that make it easier?? save me more money from having to get the p72 chip and THEN tune??

and from a good tune, how much hp can i expect to get??
