What is your ultra lean burn range now? I remember you were using a CX/VX transmission IIRC to keep RPMs down. But this car has pretty short gearing, no?

I miss the Del Sol with Neptune on a P28 ecu. The Civic before that was running a Haltech stand alone and my sons Civic was running a P28 with CROME.
My Talon lean burn range is 30 to 35:1 light load freeway, 20 to 22:1 mid load, and now 14.5 to 15.5 low boost 13 psi. and 11.8 to 12.8:1 high boost 14psi. to 50 psi.
My last Del Sol lean burn numbers were close to the same at light load freeway but every other load I was running around 11.8 to 12.8:1.
The Talon gearing is very low compared to the Del Sol. At freeway 65 to 70 mph I'm at 3000 rpm to 3100 rpm.
