Re: 5401-IMPROVING HORSEPOWER
I believe the only tuner that's approved by BMWNA is Dinan, which will not void warranty.
Going from mild to wild, you could start with CAI, engine software, tranny software (for automatic tranny), then you can go to stage II or stage III for more power. At the top of the list, go with Dinan super charge, that will add a really nice boost to the already mightly 4.4L engine, but it comes with a price, both in $$$ and longevity of the engine.
There's only one Dinan authorize dealer in MA, I think it's in Norwood.
1999 540ITA Sports, Dinan CAI & software. M5 rear swaybar. Debadged.
