We have been in the process of finalizing our stage 4 tune for a few months now, and I'm happy to report that "stage 4" kits are now complete and ready to ship. We made some changes recently to make our built motors (stages 2.5, 3 and 4) even more stout and have pushed them far beyond what they've been subjected to ever before. In this case, we took My Tran's M3 all the way to 1022rwhp where with our current configuration it wouldn't make any more. We did a ton of dyno pulls at these elevated power levels. There's a lot more that these cars are capable of (remember we're still running factory cams!), but for now, this is where we're at.
Just to give everyone an idea how much power this is... I am pretty comfortable using a drive train loss of 18% which equates to an estimated engine horsepower of 1246bhp.
1246bhp X (1 - 0.18) = 1022rwhp
I think most everyone agrees the C6 Z06 is a crazy fast car with it's 7.0 litre engine and 505hp. It has a 0-60mph time of 3.6 seconds and a 1/4 mile from the factory of 11.3! I've raced them and they're no joke. We're going to be doing things to My Tran's M3 so it will hook up, but to compare them straight power for power.... My Tran's car just made 1246hp (2.46 times more than the Z06). I haven't even driven his car on the street yet but I drove mine with 840rwhp and it was unreal.
For our production released kits, we backed the boost down ever so slightly to release our stage 4 kits at the following power levels: 720rwhp (pump), 780rwhp (pump+meth), 850rwhp (race) and 920rwhp (race+meth).

1022rwhp Uncorrected (this is what the car actually made)
986rwhp SAE corrected (this is if the dyno was corrected for a standard day)
