basically thats the WORST type of fuel management you can use. it'd really be worth it to get dyno tuned with uberdata, or if you have a ton of money, hondata.
a narrow band a/f gauge wont be able to tell you much.
im not sure about adjusting the internal. my internal is the non-adjustable. sorry i can't help there
uberdata is garbage. you can't real time tune with it and it has a lot of flaws.
as for the FMU you can make a lot of power with a FMU. I made around 300whp for 2 1/2 years on a FMU, 450cc injectors, afc, 255lph pump, and missing link.
ok this is what I think you should do. Get a inline pro head gasket. it will drop compression to 9.7:1. then get rid of that turbo because you are probably over spinning it because of your rev range. they only tend to hold boost to about 6000rpm which doesn't help you much. get hondata and 660 or bigger injectors and tune it for 10psi or so on pump and 15psi or so on C16. don't go over 300whp with stock internals.
