I have a 2009 328i with afe intake full cat back exaust and gintani tune.

I was wondering if i could add the piggy back juice box to the gintani tune would that add any thing to the car or has all the max potential already been brought out by the Gintani tune already

Any good/reputable real full tune should be better than the BMS PBX tuning parameters & should max out the power creation opportunities available for your engine.

There is no feature offered by the PBX that isn't already in a good full tune flash - including the throttle response. If you're not happy with the throttle response of the Gintani - then it is time for a new tune flash...

If you are looking for better throttle response - adding the PBX will give you their version of the throttle remap - but also their tuning parameters (which you don't want to add/mix with your full tune parameters). PBX throttle remap is too jerky anyway - I had one before I went with the Vishnu OFT tune. The OFT throttle remap is done the correct way, instead of simply 'fooling' the computer that you are at a wider open throttle setting than you actually are, & feels much better.

If you have a good full tune, there is no need for adding PBX & actually it is strongly recommended that you do NOT


The old addage 'if some is good, then more must be better' does not apply in this situation

I like it after my first gear . 2nd and third showed strong improvements but my first gear is still really leggy and slow off the line what could I do to add more pull and throttle response to my first gear because it's still horrible it didn't show any improvements after the gift and tune the other gears did
