Had a repeat customer come in for a retune on 91 and E85 after adding a few supporting mods.
Ended up tieing the 91 oct stock turbo record on our dyno, which is
339whp and has been held for about two years now. Which should give you an idea how hard it is to make that kind of power on our low reading Musting dyno, and on 91 oct, with the stock turbo.
The car actually made 340whp on a couple earlier pulls but the final tune had more torque and 1 less whp. It did claim the stock turbo 91 oct torque record on our dyno which is now
348wtq
Then we moved to E85, which measured at E78 (via GM FlexFuel sensor) since there was still some 91 in the tank, even after draining, which is normal. We have E85 tunes come back for a quick "touch-up" tune after a couple tanks, and they usually pick up a little more power.
On the "E85" tune it made:
395 whp / 400 wtq @ 28psi peak.
+56 whp / +52 wtq on E85

For reference:
Highest power on a Evo 9 stock turbo so far on our dyno is 403 whp / 402wtq (E85). This had the car doing a 11.4@120 mph, full weight, street tires, 300lb driver.
320-330whp will do 11.9-12.0 @ 115ish with a really good driver, full weight Evo.
Stock 03/04 evo = 190-210whp
Stock 05 evo = 210-215whp
Stock 06 evo = 220-230whp
Stock 08 evo = 215-230whp
Stock 09 Ralliart = 190-199whp
