I cannot recommend them enough. They are very responsive, great pricing and just generally amazing people. They did my flex fuel install and tune, here is my dyno chart. Gotta remember it's really freaking hot right now so the numbers might be a little lower. Red is 93 tune on shitty gas from Costco. Red is with e45 mix.

Since then they've helped me install an HKS BOV, CF Fenders, CF Hood, steering wheel and NOS purge kit. I don't think I'd go anywhere else at this point.

How long have you been on the tune for?

Looking to also be tuned in E40 and maxing out the stock turbo and trans reliably.

More than a year, haven't had a single problem and I am always running on the e50 tune. If you ever have any issues they respond extremely fast. They are all about reliability and won't push your car past what it can handle.

Visconti flex fuel kit.

Three flex kits I know for 100% fact work with MHD, from my own experience. You just need to make sure you select the correct one in your .BIN or your tune settings screen in the phone app.

MHD (Select MHD)
BM3 (Select Zeitronix, uses same CAN ID as Zeitronix)
Visconti (Just uses zeitronix hardware) (Select Zeitronix)

They all use the exact same Continental ethanol sensor.
