Throw those stupid solenoids away! They are junk!
I have figured out that they are my problem. Bad n2o noid, then the purge noid dies the next day. The Fuel noid is new, but will be replaced by a cheater in spring.
So at 5000 rpms my engine was just choking on fuel as the n2o noid was dead and not spraying!....
So the plan for spring is to blueprint my injectors, switch to Cheaters for n2o/fuel and DYNO this baby!......
And KRIS, let it fly dude!!!
