nope no reason too! Look into ecuflash! you can setup even ecu controlled boost and all you need is the software which is free and the cable for it is way cheaper then buying emanage , all the sensors and someone to tune it.
There are write ups in the tech section for ecuflash! incrediable software, that is what my 8 is tuned with and My X will be tuned with the day I pick it up!
There is definitely no reason to use the emanage. Tuning with the stock ECU has come a long way over the years. SicLanEvo is right, ECUFlash is the way to go for tuning, and you should download EvoScan for 25 bucks to log the Evo.
