	4 Bar FPR and pump need tuning? « on: August 27, 2022, 07:52:04 AM »

Hello,

I ordered a new 4 bar fuel pump and FPR for the 180 AJQ Audi TT which originaly use 3 bar parts. Will this need tuning to run, or would it be fine after installing?

You have to completely redo your fueling, since youre increasing the injector flow

Im not changing the injectors. Its just preventive maintanance, and whilest doing that, I have the option to go 4bar. Just in case I do want to go bigger injectors some time.

Its just the pump and FPR

You need to adjust fuelling if you replace the fpr to 4 bar. Observe what will happen without any changes.
