I haven't had the bumper off yet. I tapped for the IAT probe next to the boost gauge location.
I just received the CM30 Johnson pump today from LET and the pump manual doesn't mention about different pump modes/cycles. Just flow rate at different head distances.
I'm going to try something different with the HE - it might just work but I am still not sure (if not I will buy LET's HE - that thing is HUGE!!) - but it still won't be the optimum 1/4 mile setup (your MOD is perfect for the 1/4 mile) - I only plan on tracking once or twice out of personal curiosity to see what kind of beast I have built. I also have some additional heat reduction mods in store - I will post them and the measured results when I am done.
I'm itchin' to rip the bumper off tonight and get started - but I have a friend flying in tomorrow and I am going to pick her up at the AP - she wants to see my SRT so the mods will have to wait for the weekend..
