You'll probably run out of injector...I thought about it too. Some things come to mind -
The stock TBI fuel pump probably won't be sufficient, an EP381 from a 96 Vortec system could.
It'll need a 2BAR MAP sensor to effectively control SA and VE. The EBL Flash-II is set up to control boost and the bottle but, it'll need a separate Trans controller in your case, unless you go with a manual trans.
Otherwise your 7427 PCM will need tuning, maybe with a Moates Emulator or converting to a flash chip like the SST 27SF512 and using TunerPro RT software. Either ECM option can work, they are both running at 8192 Baud rate so, they're fast enough.
IMO, the TBI can be used for blow through injection since the fuel regulator is pressurized and you can jack it up to counteract the pressure from boost but, A VRFPR would help with that. YMMV
Fuel is gonna be your limiting factor.ok i was thinking i could have it tuned to run a turbo but did not know thank you although i would not feel comfortable burning a chip do you know any company that you can send a stock chip out and tell them what you have and them burn it. also what would be the limit for boost that the tbi could take
