The s60R has a Chip only . The M3 is Smg & has a Dinan Intake and Dinan software.
Found this on SS forum. Pretty freekin fast for a Volvo. Btw- This Chip added 45-50 Hp not bad for $800.

Both these guys are my freinds . The R is just insanely fast for just a chip. Plus it's a automatic. This R also ripped a 2005 S4 last week but video isn't working. It's a pretty good alternative if you need a 4 door sleeper. I know most of you wil say "it's a cab" but this cab took a 6 speed coupe ( he has the video) plus it has some mods..
IMO The difference between a cab and coupe is very marginal. With equal drivers, theoretically the coupe should pull. In real life you cannot even cout 2 tenths of a second so a driver's error could easily make up that time.
Hence anothe reason why SMG is faster all the time.
I love my Sti but gotta give props to the S60R. He has a exhaust /intake/ downpipe on order which will give it close to 375-380 hp!! It handles insane too. He has front/rear sway bars and springs along with the 4 c advanced suspension it comes with
