I just don't think that an engine management solution that's that limited in what it has to offer can really be considered serving it's purpose though. Yah, it'll work for a low boost set up, but when there's plenty of alternatives available that will work just as well, with much more potential for growth, it doesn't seem like a good alternative to me.

I suppose this also asks the question, why can they not handle injectors larger than 150% successfully? It's certainly not due to an issue with programming or anything else, etc. Likely, it's due to the feedback that occurs when using a piggyback... the ecu makes changes, and due to a much larger injector, the changes are amplified... an inherent issue with using piggybacks. (Worth mentioning that I don't know this is the case... this is a common issue with other piggybacks, and while I presume applies here, I can't say for certain).
