4bar fpr+pump+costum chip
I have S3 1.8T with unknown chip. Its running great, but max pressure is 1.5bar. Tested with VAG-COM. I think its a bit too much cause dont have any other mods.
I know one guy who makes costum maps for Audi's. He told me that i should get 4bar fuel pressure regulater and better fuel pump(walbro or bosch) and then he would write a costum map for my car. He said that with 1.5bar there is probably not enough fuel and its pointless.
What you guys think? Should i go for these mods and costum map? Like to have a bit more power than at the moment with 0 mods and some unknown chip.
