Update: I'm ready too start this stage 1 tune thread but I have one problem! I cant seem to find my system to lean off idle problem! I've logged and everything. Pressure tested/smoked the whole system, cam follower was inspected, pcv is new, maf is fine/unplugged to see if that was the cause. Diverter valve is brand new, last one failed. I've done it all except changed high pressure fuel pump or fuel filter. I don't swap parts until I verified they are bad. What are your guy's thoughts? I was to start tuning it but I cant without it being properly running.
Also rail pressure is 4-5 bar high pressure side follows requested.

Put the stock intake system back on. Doing a community tune thread, you'd want that stock anyway.

Sad part is I bought it with the aftermarket intake. Does anybody have an extra intake around? I'll pay shipping.

Here is a map of all the maps in the stage one. Except the fueling safety maps were giving me problems. Can someone correct it for me? Thanks.

I wonder if it's the module or lpfp itself? Can you get back to us after the lpfp install. It's the only thing left it could be.

I'm almost thinking it may be because my software and epprom isn't the correct one, my ecu is a 7115b 010 file and the file im using is a stock 7115h 030 file, I will know tomorrow when I receive my bdm reader and I'm going to need to immo off my stage 1+ untrionic ecu that was the car oem before I got the dealer to do a  ecu swap, when I use the stock 7115b I can a error in group 60 tba

I actually used another eeprom and bin file to verify this. No change. I am dead set on this lpfp. It's the only thing left.

I could be wrong but after verifying everything what else could it be? Other than the module it's self possibly. The one being the drivers seat I believe. But I think it's the pump. Anybody else have a say in this?
