[QUOTE="556129, post: 367960, member: 14979"] This is fantastic news: [I]Jan 2007 To put aside any doubts about how much are the actual gains, a before and after dyno on the M54 2.171 cc engine was done. Factory specs: a. 170 bhp at 6100rpm b. 210Nm at 3500 rpm Dyno before ecu flash: a. 174 bhp at 6100 rpm (178 bhp at 6300 rpm) b. 218 Nm at 3750rpm (The car has some light mods, namely GruppeM, supersprint muffler, broquet and Volk Racing spark plugs. These may have pushed the power and torque marginally above factory specs.) [B]Dyno after ecu flash: a. 194 bhp at 6100rpm (198 at 6300 rpm) b. 242 Nm at 3900rpm[/B][/I][B][/B] Sounds like the perf specs for a 525i. Mine's a 520i 2.2 and it certainly needs all the help it can get from a remapping. Do let me know if this Bernard guy is in town again! and I hope to hear reviews from the rest of you that got flashed by him. Cheers [/QUOTE]
