Got mine installed and did an adaptation. Ive had 2 stalls so far in about 100 miles. Once yesterday and once today. Today was as soon as I put it in reverse, it died. Started back up and then drove through stop n go and highway traffic for 35 miles with no issue. I don't know.
I've had a boost leak (green o ring) for the last few weeks and that was addressed at the same time as the tb install so can't say what kind of difference I notice in power. In responsiveness, it is noticeable. It makes it feel more like an old school throttle cable equipped car. You move the pedal, you feel the response instantly. No hesitation or thinking about it anymore. Even on very small throttle inputs at low rpm, you feel instant response.
I'll see what a revision of my tune will do in the next few weeks
As far as worth the money, at this point with how much I've spent (and many on here are way deeper in it than me) it's worth it. For others, with how little of a gain, there would be other things that I'd do first then leave this for last. Unless you're tracking the car and throttle input is key.
