I recently got 2 new turbos installed that were upgraded by turbolabs of America and now when I am trying to do WOT pulls for map 5 to learn or in map 2, I get black smoke around 6k rpm and the car sputters and hesitates. Other than that, the car pulls hard and boosts quickly. Current mods:
Upgraded compressor wheel turbos from turbolabs of america
MMP silicone inlets
ARM outlets
5" intercooler
Charge pipe
3" ******* *********
berk street exhaust
Single weight flywheel
550I clutch and pressure plate
JB4

I have attached 2 datalogs. One is a 3rd gear pull and the other a 4th gear pull. Something to note, on the datalog pulls 4th gear did not hesitate and blow smoke, but 3rd gear did. From what I can see, and I am new to the datalogging, it looks like I'm losing fuel pressure on the high side. I'm thinking I need to upgrade my fuels system, but would like a second opinion before I drop the money for the upgrade right now. Thanks for the help.

Upload the log files as is without converting into pdf so it can be read easily,

So far your low fuel pump dropping below 50

Maybe u can try to lower you FOL from 90 to 80 or 70 and see if it make difference.

By the way are you running any flash or tune?

Ok, I will upload the excel sheets when I get home to my computer. What is FOL? Not familiar with that acronym. Also, I am not running a tune.

I wouldnt run this car until fueling is addressed. Timing is very poor and fueling cant keep up. Lpfp drops too low and hpfp tanks because of it.
