For piggyback ECU the only ones worth using are the Emanage Ultimate(its what I use) and the AEM FIC. Higher boost programs? I dont know what you are asking as far as hondata the only thing that is similiar is the Dezod/APR unit I dont really know anyone running it atleast on the forums... there are standalones Hydra, Haltech, AEM, and PROEFI. Hydra and PROEFI are the only ones backed through the actual company making the unit. AEM EMS is modified unit made to work with the tc and you have to get through DEZOD im not sure if you can get warranty through DEZOD or not. The Haltech unit is made through Ptuning dont know how that works either with warranty. Either way if you're looking to boost I'd stick with Ptuning and Dezod for your needs both are VERY reputable companies and both have Excellent customer support
