Welcome to the board. You might try posting this over on the DIY-PROM board. Some other things to try.....read and re-read this article......https://www.thirdgen.org/newdesign/tech/promintro.shtml

It is really important to know how the TPI system works and more importantly, how an engine works, How changing fuel and spark affect the engine. While Im not sure about the 165 ecm, Id say your stumble is due to the cam's lack of vacuum at lower rpms.....but not 100% sure. Read ALL the articles on PROM tuning, then post on the DIY-PROM board....look for TRAXION on there...he'll help ya. Good luck...

 

FWIW, SLP has 25lb injectors for $99 right now.....check them out.
