I was originally going to have my 2004 163bhp A4 b6 1.8T avant chipped by MTM but it now turns out the supplier in Ireland has to take out my ECU and ship it over to Germany to have the relevant work carried out, this will mean my car would be of the road for 3-4 days which doesn't suit me. So my next option is Revo, I believe you can drive in and have the relevant work carried out while you wait.
1. How do you Revo guys rate the product?
2. Which should I go for?
3. What is the difference in preformance like?
Thanks in advance for any advice.
