2001.5 Audi B5 S4

---

This Audi B5 S4 is actually the first car I ever had. Although it wasn't running until almost 7 years of owning it the wait was well worth it. As many of you know these cars come factory twin turbo which isn't the greatest since when anything goes wrong with the turbos you need to take the motor out which is why single turbo is the answer. The car being single turbo is much easier to work on and if the turbo blows up I can swap a new turbo on in 30 minutes. Then the ECU on my car is a Haltech Elite 2500 which is a top tier brand with excellent customer service and it's pretty easy to find tuners for them. The factory ECU that comes on these cars is called the ME7 which a lot of people run with upgraded twin turbos and single turbo setups with big power but it is a old ECU so tuners can be hard to find and lacking MANY new things the Haltech has to offer. Down below is all the specs on what the car has in it.
