I have a Haltech F7C EFI only computer from a previous engine conversion. Is it worth putting it onto my stock standard EFI 6 Calais. Will i get much more power or better economy out of it or am I better off spending my $600 elsewhere.
Thanks Chris![]()
I previously used to run a Haltec E6x on my Hot EFI 202, with coil packs, made a huge difference to the engine especially in traffic it used to fuel up terribly, also up high It made power for an extra 500rpm 200rpm more than the cam spec.
I dont know for a stocker but for a modded 202 definitely worth it
cheers

Sorry to bring back old threads -
Does the E6X plug straight in on the VK EFI or do you have to rewire?
Cheers
