errr, not really, let me put it this way, a stock MPS runs ~9.5 - 10:1 afr, one of the adavantges of tuning is the ability to lean this out to roughly a 12:1 afr, this is done by reducing the amount of fuel injected in relation to the amount of air ingested.
A calculation done by the MAF sensor on an stock diameter sized inlet, if you run that same calculation on a larger diameter inlet, the ECU still believes it is a stock sized inlet and fuels accordingly, when in reality the larger inlet diameter is allowing more air to enter than fuel has been allowed for, in short the engine runs leaner than intended and can go boom, before you have even realised that your dashhawk is reading dangerously lean, this is why tuning is done on a dyno, the tuner can focus soleley on the numbers without also having to think about traffic and all the other distractions of road driving. Hope this made sense.
By all means buy the Xede, just dont use it until it is properly tuned with your intake.
