Making that power I would of said as its not a standard t3 imo.

Mine never made that running greens t3 @22 psi -34 etc.Anymore would be overspeed would it not plus i wouldnt like to chance greens for over 330.
If you have had it on the rollers and done 346 I am very impressed.Before I replaced my knackered turbo,act and cooler mine did 310 !! At a "guess" which is silly I know.I would of said mine was 320-330.
