Okay I picked up some 7/12 injectors with large feed body’s and vco nozzles and was wondering what I need to set my can bus fueling to  get these to fuel right it’s fueling  way to hard

Have you read through the Quadzilla tuning procedure? Are you running with the wiretap on?    

Start at about 80% and work your way up. 

 

Also I would have to know several other factors. 

• Tires size
• Axle ratio
• Transmission
• Injector pop pressure
• Turbo 

Yeah I have ran it on wire tap and with out and still fueling hard  it’s drivable on 0 bit of you go to get in it it covers the hole road behind me and  I made a tune with it wire tap where it don’t come on to about 15 psi of boost and start the canbus fueling at like 80

Did you follow the directions in section 2 for how to get started?   It lays out how to find your starting % 

 

 

Injectors are 3000 pop and 35 inch tire  has a Borg364.5/73/14cm  and has a billet duel disc converter stage 2 clutches had shafts   it’s a sport I think the gear are 3.54 and 

Oh my this is going be impossible to clean up.

35 inch tire

Tires being 35 inch tires your final ratio is too low at 3.21:1. This is going to require lots of fuel to get turning. Optimal you would need 4.10 gear to fix this. Like myself I swapped out to 30" tires this raise the final ratio to 3.69:1, more torque to the ground, extremely low EGT's, no smoke at all. 650*F at 80 MPH at 2,450 RPM in 5th gear.

 

What size injectors?  (Found it ( 7x 0.012) injectors in the first post)

3,000 pop is too low. Stock starts at 4,500 PSI or 310 bar. I'm even using 320 bar (4,641 PSI).

Turbo in my opinion is too big. Spools too late. Hence your smoke, you can't spool that big turbo quick enough quick enough. Optimally 62/68/12 will support 150 HP injectors up to 200 HP injectors. I'm even running HX35/40 hybrid (60/60/12) with 150 HP (7 x 0.010) @ 320 bar which spools extremely fast and giving me just at 47 to 49 PSI of boost.

 

Still think the turbo is too big.
