Question about my Factory Freak WS6: 343/361 I had my 2002 WS6 M6 dyno'd at Straightline Performance on the 28th of June. I was estimating my car to put down 325/330. I was blown away when Mike said she put down 343/361.
323.8 @ 5505 RPM/ SAE Corrected: 342.5
341.5 @ 3994 RPM/ SAE Corrected: 360.8
Mods:
-Lid
-Ported TB
-Exhaust Cut-out before the axle
Everything else is stock. Stock 241's, stock pulley, stock LS6 intake, stock exhaust manifolds, stock y-pipe and stock catback. They did swap out the fuel injectors for 42 pound injectors for the 175 shot nitrous tune that didn't go as planned (Nitrous solenoid was leaking). I was also lugging 17 x 10.5" TTM's with 315 Nitto 555R's.
StraightLine Performance uses a Mustang Dyno and not a DynoJet also.
Now what I was wondering, could the dealer have put in a LS2 in my vehicle? I spun a bearing during '07 and thank God for warranties they covered it. They replaced the block and rotating assembly. I am jus' speculating at this point but how could I tell the difference between the LS1 block and the LS2 block?
Thanks!

100% its not a LS2 cause they'll have to get a custom aftermarket harness for it and thats not the kind of things a dealer want to do, plus custom tune the thing with LS6 intake and other non LS2 parts like heads and ****..
Just a good running LS1 with LS6 intake and some minor mods.

Crankshaft/cam sensors are black for 24x/2x Gen III and light grey for Gen IV 58x/4x if you wanna verify without opening something. Plus knock are on the side of the block for Gen IV instead of under intake for Gen III.

Ok, I looked up the paperwork from '07 and they did install an LS1 block in. I also found out that instead of replacing the LS6 clutch, they swapped in an LS1 clutch instead. 
Maybe the correction factor was off, I don't know. It was tuned by Mike and Straightline who is an awesome tuner. He was tweaking the tunes of 2 other cars before me on that particular day. One was my friend's brother's WS6 M6 and put down 430-something with:
T-Rex Cam
FAST 90/90
Ported 243's
ASP Pulley
Headers
Borla Catback
Seems jus' a tad lower than I would have thought it would put down. Mike was surprised with the results too and said I was putting out what Lid, Exhaust and Header F-Bodies put down.

Exactly. A dyno is true to only to itself. The numbers are not meant to be cross examined. The idea behind the dyno is the same conditions each and every time to facilitate tuning, no matter what the conditions are.

Sorry don't like mustang dynos for anything other than tuning. Too easy to just play with the numbers. Local mustang dyno place first said they set it to "dynojet equivalent",then said they set it to mustang setting and then said they set it to "where it felt right". Buddies car put out less power the second time then first and he added mods.
Just go to a dynojet but doubt your car is a real freak. Not many of them out there.I would think 340 to 350 rwhp on dynojet with lid,cutout and ported tb are very doable the 2002 are known for around 325hp in six speed form,pretty common for them.Especially with some tuning ,factory sets up these cars pretty darn rich and leaves power on the table.
