My 11’ 128i also has this slight throttle response delay I’ve noticed when doing some spirited driving. I’m replacing my CKP sensor since my car actually threw a code for it, I’m hoping that maybe it’s just an issue with the sensor reference causing the delay.

Hate to say it, but MILVS are out of stock

This is a heck of a thread revival.

Kgolf sold his car years ago and he was using it to compete in SCCA STX class so MILVs would not be a legal mod.

Do people still use AA tunes? Seems like there's several better options out there now.

If you want a set of MILVs you need to email Marty and make sure he gives you a heads up when he gets them back in stock. I was pinging him about them all last year and he finally got a batch delivered in November, they were sold out again within 2 weeks.
