I approached this from a different angle...I used my car as Buschur 91 octane "Mule" and then when that was optimized Al put the race gas map back in I filled the tank with 116 and we then spent the next 3 hours making my Buschur Stage IV fly on the high Octane stuff 11.9/12.1 Air/Fuel ratios...@ 24 psi peak taper to 21 at rev limiter... I then use the Apexi SAFC to ADD fuel and turn down the boost to 18 for the 91 octane... anything else saw the ECU pulling timing and power dropped rapidly....My EVO runs @ 10.9 to 11.1 on the "Daily Driver" settings with "only" about 330 WHP (per the G-tech) But the Race set-up sees about 380 whp and is completely monitored by the factory ECU... I still have the MAS restrictions but the car starts evert cold morning and idles like stock with the 264's..and as the Thunderhill times show the car is insanely fast...My run partners wern't the other evos or even the TT Supras...they were Z06s, Vipers, and stripped and trailered race cars...on slicks.:-)... Follow the link...Oh and while caravaning back, when the other EVOs needed 13 gallons my car only drank 9 to 10 max...

 

the link oops, http://www.speedventures.net/event_results_db.asp? guess which time belongs to the "UberEVO"
