Hello SIR ,

Big trouble for me , (sorry for my poor english), brand new promag 12 ,8139+ 8106 ignition box : all installed on our 565 ci blown alcohol bbc , engine start well , but do not rev more than about 5000/5500 rpm ... ! engine has no power !!
check all connections , grounds ..., etc , everything looks good .
the kill switch( that work) is the one delivered with box , we connect it with bigger wires ( 16 gauge), could it be the problem ?
we also try to connect an autometer tach with your converter box , and did not work , so disconnect everything , except the kill switch , but did not change engine problems ..
our fuel injection system is new and checked more than 10 times !
if we do open the throtle 75%, briefly, during heating in the stands , fuel escape from the small holes in the port nozzles.. like some fuel not burning .. and going back ..

Please do need help :huh:
Thanks , JO
