Its cool youre running an FCON...Ive heard those are the trick setups to have, presuming you have the patience to take it to an authorized tuner for it all the time. I dont guess you have the problem lol Ive heard they are very consistent and make excellent power, but I like the ability to tweak on things myself LOL One of the baddest supras I know of runs that setup.
Keep in mind that the 350 is starting with .5 liter more displacement, and it was developed with many years advancement in engine technology than the venerable inline toyota motor. I would wager that, if the 2jz supra had been introduced in 2003 with the exact same engine, tuners would have made rediculous power right out of the gate... The engine management and turbo technology is so much better now that 10 years ago that it would have been a no-brainer.
Anyway, Ill let you and fahque continue...sorry to bust in.
Im sending you a PM about this...lets see if we can get-up for friendly run sometime ourselves
