hi im new to posting i have been reading many other posts in various sections and now i think i am ready to set my HP goals. i has thinking of going with the tweakit.com ida 55mm 53mm 50mm taperd bore, weber six port manifold and this is were i come acrost my first posible problem?? obviously with out the 6pi actuators the 6th port is always goin to be open causing me to lose low end correct? is there any way to fix this? posibly blocking off the 6th port all together? i am also goin to use pinaple racings large street port templates for the intake and exhaust ports. i am thinking of buying the haltech e6x stand alone.. i have experience with tuning i have a hp tuner in my pontiac. i was estimating somewere around 200 as far as horse power. is this acurate and besides sensors like wide band , ex temp, and map what am i missing in this build?
