94 accord 5sp f22b2 w/p28 cobrartp and HTS

So I've gone through the process of building a base map for the DSM blue top injectors I installed. I feel like I'm missing something here. Thing will fire up but barely idle. Have to keep it alive with my foot and wide band reads super lean 3.8v in HTS.
BUT..... I can start it up on a pretty much stock P28 map and it starts and idles just fine with the wideband reading about 9-11 afr at idle.
Any ideas on what I could check on?

 

Been messing around all weekend with this thing. It runs smoothly on a p28 map but just rich. Even in 5psi boost it's fine but just rich.

But when using a map rescaled for yhe 450cc injectors it is lean as hell and baaaarely runs.

 

Hint, don't set the injector value to 450. Increase or decrease that # in increments of 10 until it runs more right. Increase should lean it out. Dial it in with smaller increments once you are in the ballpark

 

Interesting....🤔
So instead of starting out the "New injector " column to 450cc in the set up section, just slowly increase the number from the stock 240cc and increase it till AFRs get closer to my target? Might give that a shot next time I get into the car.
