what really got my attention was how much smoother the power delievery is. i mean damn the jwt look like its doing jump n jacks.
however i've read in scc on project silvia that went straight to jwt to get their ecu done, and the result was 30 more whp. its like what wdracing said, the difference would be minimal if you compared a off the shelf vs off the shelf, or custom vs custom
But the Enthalpy ECU, the one that goes for $650 from BD is "off the shelf..." It's plug and play, no tuning required...what I'm gathering from these posts is that the ECU that had 40 more whp was tuned more aggressively than the ECU's that Enthalpy offers off the shelf through BD. But like WD said, timing makes a HUGE difference...I'd like to see an enthalpy ECU straight from BD compared to a JWT ECU + 2-3 deg. timing advance as well.
