search for viezu (you called them vizeu) in the search function on here and have a read, load of info.
Personally id go R-tech if i was down that way.
not sure if jkm is near you?
Well i nearly spelt it correct haha there is a viezu mapper in kent and looking at some of the cars they have done they look pretty well respected!
R-tech is about 2.5hour drive away and only say a stage 1 map is 280bhp where is other people with a stage 1 ed30 are saying they have over 300bhp
If you took some time to read through the many threads on this subject, all tuners claim different figures but in reality the limit is what the hardware will allow.
Nick @ R-Tech knows the TFSI engine inside out. He will do you the best possible map for your car. Its completely custom and tailored to how you want it to drive. If you want all out torque and the most power, ask for it.
IF your car can make 300bhp, then Nick will give you 300bhp. Simples.
He will thoroughly health check the car prior to mapping, and offers excellent aftersales if you have any further requirements after its mapped. Its not just a "Flash and dash" generic map that a lot of these "tuners" offer.
There is a reason why people travel from Kent / Southampton to get him to map their car
