Super Charged Methanol Lean 8500+

New Build.

GenII Super Charged Rotrex c38-91 Carpeneter Built For Methanol.

Fuel System. Fuel Tech dual speed pump 10AN out to filter to Fuel Tech regulator Y to 2 6an billet RC fuel rail.

Injectors. Primary OEM 270cc Secondary Injector Dynamics ID2000 cc.

Fuel PSI set to 60 psi and high speed pump at WOT with a 1:1 boost to regulator

Estimated HP 475-500HP

On the dyno I am lean around 8000?

Injector Balance set to 15% on primary and secondary should do 85%?

my TPS fuel map is MAXED out?

What would cause this? Does the ECU have a safe mode and cut the secondary injectors out at high RPM?

Stock is 20-80 so you are not too far off,I don't think this is your problem.Are you sure you are not loosing pressure when the upper injectors open?
