[Twix]

I've driven a Dinan tuned Z4 35i and a Dinan tuned 650i. 400lbs of TQ isn't a whole lot for me, I had a 97 T-bird and an 87 Mustang with a 410 Windsor with 3 stages of giggle gas.

The 28i is definitely faster and torquey, but it's not the animal the 35i or 50i becomes with the tune. It is, however, perfect for my needs as a daily driver that sees a lot of highway driving. Hopefully the next trip I have to drive to work, I'll reset my MPG and see how much I'll have lost.

I have plans this summer to buy a Cayman S or a 128i and strip it out and do a full racer. I'll be keeping the X1 as a daily and bike hauler .
