trannie slipping after injector install..

After I installed my 190s last weekend, and after some WOT runs, my trans feels like it is slipping going into second; my tuning is set to shift at 3800 WOT, but it is showing up at 4100k on the tachometer once it finally hits into second, and I did some more testing, and found that it is hesitant to shift into second and even one time i felt it hang real bad shifting into second. I called suncoast today, and I spoke to a troubled angry man who said the trans would throw codes even if it slipped the slightest bit, my SCT shows 0 codes, but I know I have been feeling it less solid on I going crazy?

Your not going crazy. My tranny was doing the same thing and a couple weeks later it wouldn't even move anymore. The sct hides codes. I pulled the sct completely off and drove the truck around and took it to the dealership and they ran it for codes and there came up then.

Could this be the "shift fade" I've heard of? My truck sometimes while WOT will shift it will feel like 2 soft shifts.
