1200cc injectors causing bucking?

[tsd123]

I just picked up a set of used rc 1200cc injectors. When I first put them in one of them was clogged. I made a setup to clean it my self, and now it works fine. I have been doing research trying to figure out how to set them up. My car keeps bucking mid way through a pull. It isn't really knocking, and the a/f is around 12.0. I did a boost leak test, and fixed a couple leaks. It didn't seem to help any though. I had 570cc in it before. I have a few 2nd gear pulls.

can't look at your logs until I get off work but did you get everything set up correctly to where it is idling good? also when you just drive your car normal is it acting good a/f wise?

It idles perfect. I had it idling around .25 g per rev. I change it around a little to see what makes a difference. The car will stumble after free revving it sometimes, and when slipping the clutch to back up after I let off it tries to die. I just put a throttle body on it with a isc/fiav block off. It ran good before I changed the throttle body and injectors. It has to be the injectors.

I think i'm going to switch back to the 570cc, and send the other ones to get cleaned. They might be sticking a little with higher fuel pressure. I noticed when I cleaned the one I did, I had to keep working it untill I could apply full pressure. At first if i would go full pressure it wouldn't open. I got it working, but I'm wondering if the others might have that problem.
