My biggest complaint on the AEM is the start process it has to make 2 complete revaluations to pick up the crank and cam signal and if it docent like it you have to cycle the key on and off again.
ts just not cool in a show environment modern EFI should start right up plain and simple. My other complaint is its never going to be updated its obsolete. its a great race box but not very street/show friendly mind you its never left me stranded or gave me any problems.
the FAST xfi is updated it has self learning and is a little easy to tune (IMHO) I haven't heard any complaints and is digital I don't know much about the big stuff or mega squirt.
So you want to buy it?
