That’s easy to say- not sure if you’ve installed one yet. It’s not hard- a bit tougher than installing a carb and fuel system with return line, some electrical, etc. You need to make sure your exhaust is solid and sealed up for good O2 readings. Your wiring is solid and not hack. Over all not bad to do and knowing what I know now, I’d do it again. My trouble is the programming as it’s supposed to be a “learnable system.” They are but to a point. For the FITech, there is no description of terms so you know what you are changing (adaptive) and what the end result will do. IAC and TPS are easy and self explanatory but when you change the fuel blocks one at a time to correct say a hesitation at off idle condition. That’s when it gets tricky. But I agree a lot of times poor install could be blamed and the unit scrapped for a 750 double pumper from Bobo zone. “On sale with an online coupon.”
