that's what i read too.. so i went with 9.5gallons of 100 and 4.5 gallons of 91.. that should result in some octane > 93 haha

as for chipping, etc as nos suggested.. i dunno how i feel about that.. i really like the idea of being able to wail on the car and know that it will be stone reliable as long as i am shifting cleanly.. 280hp crank is supposed to be the upper limit of what the engine can tolerate long term so i would rather have that 50hp 'buffer' in place rather than get a fraction more performance and a lot more worry. i was driving 5k-7k rpm, full boost full throttle in 2nd,3rd and 4th for about 45min non stop (sucking down gas at appx 7mpg (eat that EPA mileage ratings!!).. EGTs never got higher than 1550F, oil pressure rock solid at 90PSI..

the car i was trying to follow.. a chipped 335i making 340whp.. was a total beast.. when it was technical i could keep at his bumper (especially in tight low speed corner exit when the awd fairies are at their best) but when it straightened out.. he would walk on me like i wasn't accelerating :ph34r:
