So you dyno'd both the BAMA tune and Lund tune on the same day with the same cool down times? A dyno is a tuning tool and not a device used to measure performance.
Tell me why the tune wouldnt be updated already? Lund sets his tunes up to the point where the only thing you would need to change is if you changed CAIs (NA tunes).
-Let's think about this realistically. CAI affects the incoming air flow, tune required.
-Offroad Pipe, Catalyst Readiness tests are set to proper parameters by default to ensure a CEL is not tripped.
-Headers most certainly do not affect incoming air flow, no retune needed. O2 transport delay is self learning on the 11+ cars.
-Lund sets all of his tunes to rev over 7500 RPM, so the MAF transfer is already developed with the Boss Manifold in mind. No retune required.
Someone telling you, you get free tunes for life is selling you a bag of poo. These cars have widebands installed on both banks and are able to make Air/Fuel changes on the fly. The only thing that needs calibrated in a tune is incoming air flow and thats only if you have a CAI swap.
Now supercharged cars are a bit different.
