Yeah now the tune is close, the injector transition is a lot smoother now. Just need to lean it out and get the timing setup in the non-WOT areas and I will be ready to get tires and go to the track.
You really pushed the stock bottom end, but I knew it was only going to be so long before it blew. My friend went through the same thing on his LSx mustang. It went 143 mph on the stock bottom end, but only made about 10 passes and a few street hits.

The part throttle portion of my timing table should work good for you if you want to start there.
Pretty much everything above .56 Cyl Air.
As you can see, I had no timing in the stock motor at anything that resembled WOT. I will be adding lots more timing as soon as I can get the temperature down.

Are you talking about IAT's or ECT getting down before you add timing? If you are talking about IAT's, what do they look like to give you that kind of concern?

ECT. I've done everything to bleed the system that I can think of and I am fairly certain that I have gotten all the air out of the system. On a 30 min (at 2900-3000 RPM) drive in 90* I am hitting 232* on the datalog. I may have to move the intercooler up somehow and get the air bridge back on under the car. I was thinking of buying the Griffin but that would just be up higher and the thickness would also bring it even closer to the turbo.

I put the air bridge/pickup/dam on this morning and did a bunch of driving. That helped some and I think that I can make it work better if I trim the aluminum L bracket on the bottom of the IC. That should expose another inch or so of the air dam. The only other thing that I can do to help is space the IC forward a little more.
Then I can put the blanket on the turbo and wrap the down pipe. That should get me to 205-210 or so in the heat of a summer day.
I was working on the tune aswell so I had to get on it a bunch of times. God I missed that feeling. Shit's like crack. She felt pretty good. I did a little hit on the way home against Boner and then I was cruising easy and all of the sudden the fuel pump shut off. Switch was on. Pump was off. Everything else in the car was still on. Got out. Checked the lines. Checked the wires to the pump, went back in the car, switched it on again, and it came right on. I had a full tank of gas also so the pump wasn't cavitating or anything. Weird. Gotta keep my eye on that.

Took the car out tonite for a little tunning. It is 62* outside and the turbo LOVES IT! This is the first time that I have experienced the turbo setup outside of the usual balmy Florida summer weather of low 80* to a high of 100*.
Hopefully get my AMS 500 controller hooked up tomorrow and make some low boost passes at the track on Wednesday. It will warm up a little by wednesday but it should still be the best air that we've seen since early March.

Ill be there by 7pm at the latest. My car usually doesn't have traction issues but the test & tune prep has been sucking pretty badly lately from what I have seen. Hopefully it isn't an issue for me.

Got some passes in tonite between the rain. No good launches due to poor conditions. They didnt get the track dry until late but kudos to them for not raining it out. Anyway, I found a leak at the exhaust manifold gasket and I got some data. Not sure how to feel about the outing right now. It went 10.08 @ 127 (coasting because I hit the limiter about 50' out) @ 12 psi with a 1.60 60'. On the stock longblock it went 10.002 @ 129 (also coasting) @ 17 psi with a 1.38 60'. That's good I guess. I also had 3 more mph @ the 1/8th.

It will take some getting used to but ive been watching your thread from the start, and sounds like you know what your doing. Im also building a 377 t88 nitrous car and watching your car come to life just gives me more hope to work on mine.
