Would a GT3071R, 0.50A/R, 56trim with 0.63 Int WG exh. differ very much from a T34? The hp capabilty should be in the same region? Although better spool.
Edit: If you buy a Innovate wblm lite XD1+LC1 or LM1-kit and make logs of your engines performance at say 1 bar boost with a turbo like this, maybe you could NMS taylor you a chip? Obviously you would pay for it and maybe it would require more than one eeprom being sent over the oceans, but freight should be an expensive issue.
