I wouldn't go as far to say that the muffler delete increased HP but given the noncontrol of the ambient temp, track cond, driver error,etc there certainly doesn't seem to be any loss in HP w/ the muffler delete after giving the dme time to readjust. 
saw an e39 540i w/ vf stage I 350 rwhp

Overall I'm quite pleased w/ how this little Mroadster was doing in a straightline and to know I'm a decent driver that can pull consistent times. My point was proven and the M won't be hitting the track anymore but my nitroused truck will  |
coll write up and good info
When I get my car back from ESS I'll try and get some track info.
