GT2860 16psi no electronic boost controll stock st205 ecu?

Sat Dec 16, 2017 1:16 am

I bought a part finished project recently. The next thing thats needs doing is an aftermarket ecu with some kind of closed loop boost control, problem is I dont really have the money at the moment.
Just wondering on peoples thoughts about my set up in the interim. Im a bit concerned running the 16psi might be a bit much without an ebc and whether the stock ecu will be able to adjust the mixture enough. Also running a high volume fuel pump and 3inch straight through
exaust fmic and dump valve.

I've run a similar sized turbo on stock setup before at the same pressure. It's not ideal, but you can do it. I'd get an egt gauge and wideband to make sure you're not running excessively lean

Thanks, couple gauges might be worth the investment to keep an eye on things.
