my plans are to add a Cather (either regular or spechal, do know wich one would work better) and a tst pm3 or somthing sumular with a set of twins (stock hx-35 / B2), the truck alread has 5" exaust and f1 m2. 5 injectores. who much power should i expect to see. by my calculations, around the 450 - 500 range. with this setup is it posible to tow a 12K at altitued and not get hotter then 1200 or will the injector and catcher combo be to small to spool the turbos up fast enough? my goal is to have 550 for driving arond town and have 450 that i can use all of for towing? i have yet to figure out how im going to achive this, mybe biger injectors?
