Yep, it was the cold start stuff it was screwing up, or I should say I was screwing up because the temp sensor was reading too high lol.

Once it got to a temp where it was learning it really didn't seem to have any problems that I noticed on the fuel tables. It just corrects itself and goes on it's way.

Just something of interest. We use the 8 injector units on both cars. Over the weekend we took dad's to the dragstrip and grabbed a data log. Even with an engine making 724hp those injectors have a ton of room. At WOT and 5800 rpm peak injector duty cycle was only 43% LOL And pulling 14% fuel. So I went in and pulled 10% out of the WOT area from 2000 to 6000 rpm and the car picked up a solid 1 mph on the next pass. I didn't even open the hood.

So many cool features on these things.
