I've got some 800cc injectors but it will obviously require standalone and since im using an oem excedy clutch im thinking 340bhp would be my safe limit anyway?
Now my car has a paul port fcd. I'm going to fit a 255lph fuel pump and im seriously tempted to get it on the rollers and turn up the boost past 1.2 whilst keeping an eye on the afr. Especially if I could achieve 320-330bhp without knock and safe afr's.
I'm quite happy to keep the Toyota ecu because it's reliable and the error codes can be very useful.
You won't need to go above 1.2bar, I made 320 at 1.2bar on a standard rev3 engine with ct20b. My only limitation was my ARC side mount which was getting too hot so an st205 cc is going on at the moment.
Also you will struggle to get those number with the Toyota ecu, mine was holding the car back at 270 until I put the power fx on and had it mapped properly.

Fair enuf, I think the ct20b just becomes a hot air blower much higher than 1.2bar.
Have it set at 1.2 with a fast spool and the right level of tune and it will be an animal
Mines a hybrid rated at 360bhp at 1.5 bar so my temps should be slightly better than a stock CT20 but we shall see.
As much as id quite like to push the Toyota ecu and 540's out of pure curiosity I can get standalone fitted and mapped for a grand and I already have the 800cc injectors.
Even if I push the Toyota ecu to say 1.3 bar I'd likely get it mapped anyway knowing I'll get better results with the standalone. Like I said its curiosity lol.
