Ok I built a new aluminator and put it in my foush fobra (gt). I have a 03 cobra harness but I'm using my gt computer and dash harness just modding the 2. I've searched and found many answers but still need help with a couple. A) do I need to add another coolant temp sensor to the system? B) I'm lost on what to do with the boost bypass cylinoid c) i would like to start the car and let it run for a bit before it goes to get tunned. I planned on running the 19 pound injectors and stock Maf to get it running then swap I the new Maf and 39s when I go tune it but the clips are different. What's the chances on it running with the 39s and no tune? Or do 60 pound injectors have the same clips as the. 39s or the 19s? If there the same as 19s many I should leave them in and just go to the 60 pounders for the tune? I'm running a dumped tank and return system when it goes to the tuner and I'm thinking the 39s will be at there limits anyways. Motor combo is. Aluminator block 04 heads and cams. Ported lower. Stage 5 eaton. Welded and ported plenum ported tb. Jlt cold air intake. And right now the stock pulleys are on but for the tune it will have cogs going for 17psi. It has a fords heat exchanger with twin fans aswell. I will link my build pics in 5. Thanks Jim.
