Ive got 650cc and returnline on my 48lb S3D and Im running 23psi and Im pulling 21% at WOT with my dtec.

My Fuel pressure is set to 50psi and seeing boost, so 73psi at WOT.

Plenty of fuel.

i have a wideband and dual scan gauge and its 11.5 but the injectors duty cycle is 90%

im looking to do the same step up. but my question is do i need a FPR mod or the fuel pump wire mod?

[hshredder18]

i dont have either but im going to get the rewire for my 255

650s would be the best way to go
