Dinan exhaust - $3599.00
Dinan intercoolers - $2499.00
Stage 4 software from stage 1 - $900.00
$6998.00 + labor (about 7 hours) to go from stage 1 to stage 4.
LSD would be an additional $3600.00 + labor.

Hmm.. I already have a Dinan Stage 1 and an Eissenman Race exhaust so I figure the Inter-coolers would cost just $2500 +$900 to Stage 4 as you say. Not sure benefit of the LSD yet but looking closely.
Would like to see if anyone has done either of these big upgrades before to a 550i tho.
