P28, OBD1 P72, PM6, etc...you can get almost any OBD1 ECU chipped with the map you need to run your car....why are you doing this?

i just wana know if i can replace my OBD 2 p72 for another ECU and gain HP without needing to modifi the harnes, so will a P73 do de trick??

the only way you're going to see any gain at all is if you have some work done to the car presently and then get it tuned....just swapping ECU's isn't going to help you at damn bit....

i know that, i already have the basics, I/H/E/ msd ignition, fuel preasure regulator and cams, but im concern also about OBD2 creating memoryand adjusting to stock even with mods, like i read in other treads.thats why i want to know if thers a better OBD2 ECU.

the only better OBD2 is the P73, but that might not run your car like it wants...the BEST way is to get a Crome chipped P28 and tune...but when i did mine (for boost) it cost me $215 for the ECU, harness, chip and socketing and another $375 for tuning.....you could find a lot better use for your money....

P73 or stock....you're not going to see that large of a gain...
