So out of all this is the piggy-back ecu's like Apexi and E-greddy junk? I reported like an 18hp gain from the apexi piggy when first installed and horrible gas mileage aswell, and after installed on my sc400 for a few months the apexi piggy started fouling up on me and I had to dump it, maybe it was the re-adjusting process that was mentioned above that caused the fouling?.

I was pushing toward the stand alone ecu's for the longest time but the wiring, tuning and price turned me off. I love the idea of programming and tuning on your own laptop. That could could be the best choice yet if it is proven to perform. Keep this thread going fellas!!!!!!!
