new pro xs modding?

[imapro]

firstly a few facts
new to forum .long time reader
-i have the new 200 proxs v8.
-200-225hp have their own TB and air box assembly . 250-300 have a larger tb and box (prexisting verado TB).
-everything else identical aside from ecm.
-nobody offers tunes anymore.

my thoughts
-parts are cheap for upgrade
-ecm uses iat sensor map sensor tps and o2 sensor.

if i bolt on larger tb and air box. and also add a resistor inline on IAT sensor to show 20 deg cooler air. could it make more HP? anything noticeable?

or is the detune from 300 proxs to the 200 all gonna be timing and this wont do anything.

thanks

Sorry but I know nothing about the new stuff. Hopefully someone will jump in.
