Vr7140 and Paxton novi1200

[Berik]

Dear Diablosport,

Could you please tell me should I change any parameters with following changes:
1. Kooks headers and slp mufflers
2. throttle body from GT500
3. spark plugs autolite HT0 or NGK tr6
4. 20' wheels

Also could you please explain the "axle ratio" parameter work? What the effect from changing this parameter?

I have a problem with check engine. Predator always shows following errors:

1. Fuel delivery error
2. Fuel system too lean bank 2
3. OBD read test not complete

WHY?

Regards,

Berik

The codes you are getting are likely due to the fact that you have done mods to improve iarflow and not compensated for them inthe tune.
Considering you have added longtubes and a different TB, you should really look into some custom tuning fromone of our CMR dealers to get the car dialed in.

unfortunetly, nearest cmr dealer is 5000 km far from me. I'm from Kazakhstan, Almaty. Maybe you would find some way to help me?

You can email tunes no problem...
