Honestly man, buy a cobb.

+1, I'm having the same issue. there's absolutely no support unless you're a single turbo customer.

Very disappointed. I'm going to have to switch to COBB and have it protuned.

BMS has some solid RB turbo tuning, using their G5 ISO board and the BMS flash. It's well supported and runs strong...

So you guys think that:

29E2 Fuel injection rail, pressure sensor signal
29F2 Fuel High Pressure system

Would be fixed by a tune and not hardware?

I could be wrong, but are those not the codes that are triggered when you hit the fuel trim limits? Sounds similar to what I was getting when I had a JB4 and maxed out fuel trims with E85.

I guess each car is different in terms of tunes. I for one have no issues with codes or fuel trims on meth. My fuel trims never max out and no where close to it. Very strange but I guess all deviations in hardware as each unit built is not the same identical specs

I don't know, I'm asking. The few threads they popped up in, most people said it was HPFP related. I just want him to get the right answer and not just "switch tunes".

Yes, normally those are tuning related codes. Unless the car has long cranks which would indicate an actual high fuel pressure problem. I'm not trying to convince anyone to switch tunes. Just throwing it out there that other proven options are available that include good support.

Yes, I beleive it is, because hes pinned against the limit for a defined amount of time. He needs to either reduce OL multiplier and boost, or inject more meth. Over his many threads, people have told him to get a meth kit but instead of testing the waters to see where his trims are happy via incrementally increasing boost, he put the midrange to 20psi and is wondering why hes hitting the rail pressure limits.

I think he should switch to cobb because he has nothing but problems with his procede, and doesn't really want to learn the nuances of how it works or what its doing (albiet, is a lot of information with a language barrier). It's easier for him to switch to cobb with protune, convert the HFS3 to an HFS4 via purchasing a controller, and have the cobb protuned. Set it, test it, and forget it.
