I’m not sure he was running that on an ST as they use a completely different hpfp. And as far as I know no one makes one because I have tried for my 2.0.I am not, but the guy I bought a mountune exhaust manifold from was and swore by it. Pretty sure all he said all he did for his build was basic bolt-ons and that Mountune HPFP (which is just a rebranded XtremeD) and was making 400+whp in a ST, it sounded pretty rowdy, so I wouldn't doubt his claims. I would check out Xtreme-Di – GDI Performance Parts. I think your other option is Livernois, but they don't tune with Cobb AP to my knowledge.
FYI. The XDI HPFP requires specific changes to the hpfp configuration tables which are not released with their hpfp. You must use something like the mycal or know the tables and data to change via other tuning software.......Second you do not need the the mycal from Livernois to tune. You can tune the hpfp and injectors with any software. Just bolt on the pump and tune as usual.
He had a RS head lol, pretty cool guy tbh...gave me a killer deal on that part since he was going pte turbo!!!I’m not sure he was running that on an ST as they use a completely different hpfp. And as far as I know no one makes one because I have tried for my 2.0.

Ah got it.FYI. The XDI HPFP requires specific changes to the hpfp configuration tables which are not released with their hpfp. You must use something like the mycal or know the tables and data to change via other tuning software.
I meant that you must change the hpfp tables for the XDI or any current aftermarket hpfp using any tuning device/software that allows it. Cobb AT works as does others.Ah got it.
I was under the impression from some Livernois statements you could use access port with the setup they sell but again i may be wrong as I had them do mine.
Did you get the "evo" pump that is rated higher?I currently run the XDi HPFP and the mountune injectors. Currently tuned by Nishan. What information you looking for.
So if you go fuel rail and it fails it’s a big problem.I was wondering about reliability and since I have wmi I figured hpfp would be a cleaner install than Aux fuel rail and wmi can do the valve cleaning.
What would happen if doing a wot run and burn the aux fuel rail fuse? I am guessing it will be trouble or nothing to.worry about?
did you have to bend the hpfp fuel tube to.make it.fit? what injectors did you get? how many whp are you running. my target is 500whpSo if you go fuel rail and it fails it’s a big problem.
Not so with the hpfp and injectors. Ron Henry and I talked at length about it when I was doing mine and he also agreed if far better than a rail system because all your stock safety nets stay in place. I’m running hpfp and injectors and direct port meth at 100 percent meth and I love the setup.
looks like needs minimal bendingI did notthe Mountune kit came with everything.
