I'm going to wait until post warranty to do this. In the meantime, if I get desparate for more power I may pull the trigger on Dinan's Elite V2 computer model. I believe adding this this does not affect the factory warranty (I'll confirm prior to buying). The V2 is said to be worth 35 rwhp. Just my $.02...

i've had tons of engine and transmission work and replacements on my b58 under warranty, not willing to risk losing it...
