Again, if running a T34, i`d prefer and advise to go to 55lb injectors, then you can run the turbo flat out,
My T34.48 made 370bhp and 420lb/ft.
Greens are too small for a T34 imo thats why the boost has to tail off,
and the 55s are cheaper.
It just seems a better idea to fit bigger injectors that allow you to fuel the turbo to death if you want to, then you know your safe and you can do what you want with the boost.
My personal opinion is as a rule never have a Turbocharger that can outflow the injectors, just for safety.
If you had a boost control failure on a T34 with greens it would end in tears! on 55s you may not even notice the difference
Thats not saying what Karl does is wrong, or dangerous, im sure it works well, thae package has great reviews, but im sure given the chance even Karl would prefer to fit injectors that are more suitable.
