I think the point of the stealth is that is looks like a carb unless you are paying attention. Maybe there isn’t room inside for the ecu? I thought the next step up was the terminator which is double the price but way more powerful. I just put a regular 4150 sniper on my mild 512 it’s awesome. I can get in and drive this thing like a new car the drivability is amazing and the ecu timing control/ hyperspark distributor is a big part of that.
