How do i get better fuel economy.
I have just replaced my engine with a used one and fitted a dawes and needle valve egr block catch can egt and boost gauge .. used motor came with reco injector pump nothing else . Used all original parts from before. Before swap over . Highway travel
600ks to 3/4 tank
500ks to 3/4 tank towing
Now getting
500ks to 3/4 tank
400ks to 3/4 tank towing
Which way do i go with needle and dawes valve ?
Set to 18 psi max boost bounces to 20 for a second . Can the injector pump be adjusted still in car (and can i get a mechanical pump not using computer ? )
