Has any one used (or heard of) Chip Tuning Ltd of Bromsgrove. They aparently do dynojet setting up on their rolling road. Are they any good?

oooh , can of worms if your a volvo driver !!!!!!

had no personal experience , they obviously can do it - pick someone closer if theyre miles away .

They are about 20 miles from where I live.
Your reply makes me worried. What's the problem?
