Remember that intake temps consistently below 20C at the throttle will rob you of power. If that is true under boost as well, then you're compromising the engine's efficiency.
Older car designs used to have the air intake close to the exhaust manifold
on purpose. Fuel injection can produce rich enough mixtures to make this a practice of the past, but the reality is still that cold manifold and cylinders damage atomisation.
Of course if you're thinking of ditching the intercooler (a brave idea!) then injecting at 4-5psi is a must.
keep up the good work!
