Got the car back after over a week (felt like months)...
Injectors are in, and working. IDC is now at ~61%. But Bobby fears my stock fuel pump may take a dump so he recommended definitely going ahead and getting a Walbro 255 and a new assembly kit. So will do that soon probably since it's not crazy expensive.
Southbend Clutch & Flywheel are in and the car feels great so far. Chatter is about the same as ACT. Pedal is a bit stiffer than my ACT was. But I cant wait to see how it grabs at the dragstrip. I should be well into the 12s now with a healthier clutch.
Headers picked up great power. I am very happy with the outcome. Picked up a lot of midrange power as well as some peak power. Now sitting at 311whp and 266tq. This is, of course, on CIN's mustang dyno, and today the temperature read 98 degrees when I was at CIN.
I will try to get a soundclip for you guys tomorrow since that's probably what yall want more than anything

Nice numbers! Yeah, try 3 weeks waiting on Nissan to ship a transmission. lol That's pretty conservative on the IDC. Lots of extra cushion. How's the drivability on the new clutch? I wish I would have went with a stage 3, but Joe told me that the stage 2 should hold up fine even with some racing here and there.

I hope that you can hook up well at the track Bmurray! I say that because I'm just stg. 2 and my street 285s break loose way easily. I will most likely go to softer compound next set, like R888s even though I don't hit the track, being SC with that clutch/flywheel is too much for my street tires.

I'd like to know what your numbers would be on a dynojet dyno. Mine put done 289/256 (dynojet dyno) on my current setup. Mods: Weapon R CAI(garbage), PPE lontubes, AAM Y, AAM single, Z1 lightweight flywheel/Z1 full face sprung disk, Z1 CSC delete and uprev tune. Waiting for all my components to come in to build 3 inch intakes then a retune soon after.
50% duty on those injectors, that's a bit low no? Enough to get a good fine mist versus it just kinda "dripping". At least that's how my tuner described it to me.

It's a bit "jerkier" than my ACT was. But not bad at all. Just gotta get used to it.
thanks!
Hooking up isn't really a issue since I used MT Et Streets at the track

2007.
Just talked to my Tuner, he has me upgrading my fuel pump before I bring the car in to retune for the 3" intakes. Gonna go with the Walboro 255lph that Z1 sells.

I just ordered my walbro 255 today. $85.00 with install kit from eBay. Curious as to why he has you upgrading your fuel pump if you still have stock injectors and still at only 51% duty cycle

I'm talking about yours Brandon. I mentioned to him your plans and injector duty #'s and he said I need to upgrade my fuel pump but he will see about the injectors when we get it on the dyno for the retune as to whether or not I'll need them.
