and member csu87 has provided some nice comparisons using a virtual dyno, his baseline reading was 271whp and saw 319whp for stage 1: http://www.e90post.com/forums/showthread.php?t=1143516

a true before and after dyno comparison would be awesome. i've actually never done it myself, a quick google search shows local shop charging $60/half hour for a 2wd dyno - is that reasonable?

either way for me i'd have to wait for more parts and cooler weather, don't think any testing in 110*F would be ideal
$60 for a half hour sounds reasonable. We pay more than that but we haven't shopped around.
