Guys, I'd like to know what can cause my engine to go lean when the secondary injectors come online. It has done this since I got it running. During my dyno tune, wherever we set the secondary injectors to come on 3k to 5k, The engine would spike lean for a little less than a second then be fine. In thinking about it, the only thing I can think of as the problem is the Microtech is somehow bad (LTX-8). Anybody got any ideas what else could be wrong? And on a related note, what's it cost for a factory repair of these ECU's? I'm thinking I may need to send it back. Thanks for any help.

Current setup;
Stock T2 motor
BNR stage 3 turbo
1600cc secondary injectors
TID mod
Racing Beat turbo back exhaust
Microtech LTX-8 ECU

It could also be your grounding. I had a same problem. After putting some new and thicker gauge the problem went away.
