AFAIK, the TU pump often cuts out at e50 its recommended to use it with a flex fuel kit that can adjust the tune accordingly and eliminate the fuel cut out issue all together since the TU pump can't flow enough.

Correct, you can't run full e50 on the tu pump without issues. You either need a better pump or you can reach out to ptf and they will give you a new map to run on e45 to e50 that's slightly less aggressive

Yikes... $500 later... That is disappointing to hear. I guess I'll have a very slightly used TU pump for sale soon. 🤣😂

Yeah. Most people don't know that because all the mhd guys can run it since mhd isn't as aggressive power wise.

Ugh... That was probably why I got confused. Originally I was gonna run MHD, but ultimately decided on BM3 for map editing. Sigh... Live and learn I guess. 😁

On the positive side. If you plan on staying ots maps and change the pump you'll make more power.

I was running BM3 Stage 2 93 OTS pump on my TU pump but my fuel is shit, so I switched to Stage 2 91 OTS and timing corrections cleaned up a great deal. Car is much happier with this map.

I usually run the Stage 2+ E50 tune though because the power is incredible and addicting

Have you had any issues running the OTS e50 map on the tu pump?

Most people do.. you need a better pump for the bm3 e50 map.
With that being said, if you have the tu pump you can contact them through their support and they will send you an updated map that is slightly less aggressive so it works woth the tu pump.

Nope no issues other than the time where I accidentally went over E50 and the car wasn't running right. I think E30 is the sweet spot with the Stage 2+ E30 tune, but E50 rips as well.

Some people can't get to a true e50 on the tu pump.. it's best to assume that you can't.
