Sup guys , Need some help here please, I just bought a STS turbo kit for my 06 silverado 4x4 I got wit a 70mm Turbonetics My engine is a lq4 with a 4'' stroke fully build , what injector size will work best form y setup the turbo can flow enough for 800hp im looking about 750 I was cosidering getting some 72lbs but i think i will be cutting it close what size do u recomend will work best for my setup im using HPTUNERS to tune my PCM also I do not know how big of an injector the stock PCM will handle .

This is a street truck I use it most of the time and I also put race fuel when I hit the track.
