My dyno vid. The heart breaker Mustang dyno calculated 414WHP and 460 WTQ. Guy said to add 15% to get Dynojet numbers which is 476WHP and 529WTQ. Density altitude was also 5800 ft that day! I was not expecting any HUGE power gains from the stage one upgrade put I think 470WHP is pretty damn good for the altitude i'm at and if anyone is curious about the turbo install, it took me 15 straight hours putting those suckers in. Big PITA but worth the knuckle busters.
HUGE THANKS to Terry Burger and Tony Vargas. Both of these guys have given me unbeatable customer service the past few weeks. Great experience working with both of you and I highly recommend them.
Mods are as follows:
- 08 135i N54
- Vargas Stage 1 Turbos with Billet wheels
- BMS Intake, BMS Charge pipe,AR DPs, Stock mids, berk race muffler delete
- JB4 G5 Map 3 75 Meth Additive with RACE DME flash
- MS-109 and 100% meth injection (Single CM12 nozzle)

These seem to hold boost very well and taper off much more slowly than stock turbos. If you look at the log he is hitting close to 17.5 lbs of boost at 7k. A ton more than what you are able to hit on stock turbos (15 tops IIRC).
