Need tune help on supercharged 4.0

Bought a 2014 Tacoma supercharged with a magnuson supercharger. The bully dog tuner on it seems to be running it a lean or rich. Is there any new tunes for the bully dog that will fix this? Also have a vr tuner from my last Tacoma. It keeps throwing a air/fuel ratio sensor

 

Have you contacted Magnuson or Bully Dog?

Another option is to get it custom tuned!

Usually the Canned tuned are garbage

 

How do you know its lean or rich ? can you provide AFR logs?

You're 100% sure that the narrow band o2's are in perfect working condition? you know the OEM sensors are a consumable?

 

sounds like you need a TRD flashed ECU and some HPTuner love.

 

+1. LOTS of good info and experienced assistance available in the TRD/ Magnuson 4.0 Supercharger Tips, Tricks, and Mods and HP Tuners for 2005-2015.

@JustDSM is the man for engine tuning, while @nd4spdbh is the resident AT guru.

 

Fixed! Haha, I wouldnt call me a guru, just enough to understand whats going on and lots of trial and error.

 

Sorry had a lot going on. It was the tuner. The afr was below 8 and fried my engine. Dealer is putting a low mileage engine in the truck and there having an engine shop tune it correctly thanks everyone for the advice. Believe there gonna keep the bully dog tuner but there gonna modify it so everything is running in correct order
