Title: 4 Bar FPR and pump need tuning? Post by: denniss112 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?

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.

You need to adjust fuelling if you replace the fpr to 4 bar. Observe what will happen without any changes.Its just the pump and FPR |
