I thought I'd edit this again, as before it was quite lengthy and long winded.
Had my car remapped by Shark Performance in Mansfield. I'm happy with the Map, the service was decent, and they seem to come across as they care about their client base. I opted for them as the reviews on sites such as seatcupra/briskoda/tyresmoke seemed good.
Car is a Leon FR TDI.
What they offer;
Stage 1 is 200bhp/430nm
Stage 2 is 215bhp/450nm.
Stage 2 does require a modified exhaust system (so milltek/custom jobby), panel filter and dpf removal. The manager at shark did say (based on the owners recommendation) a air intake is needed for stage 2. Though, I would have to disagree with that as panel filter is the best filter for my car. They were possibly trying to sell me one but I didn't dwell further on it.
I opted for a stage 1. Compared to the superchips bluefin this is in a different league. The torque has increased and it does pull all the way upto the limiter. As with the bluefin it ran out of puff after 4krpm. I'm happy with the map and the car feels more alive. The car feels faster then 200bhp, but I will only know at Santa pod in september.
With a boost leak I managed a 15.3 @ 93 something. Launches were wheel spin galore though.
If I can get into late 14's I will be happy.
Please do note, if you have the dpf removed like me, it will need coding out. This is a separate cost and do go in with your eyes open. I was charged half the price + map. It sucks, but it's a business so that's what they charge. I did not know this and thought it was free, but only some places can code it out properly so the car doesn't regenerate.
Bluefin did not have this, and superchips will not code it out what so ever. So on some occasions when trying to regen, the car would cut out when slowing down. It was weird, it would also try to regen when driving.
I would use them again, my only feedback is I wish they had told me the estimated wait time. I waited a while which got a little tedious but I was offered refreshments. They're a busy bunch and the value of cars at their premises suggested they're a good outfit.
I would use them again.
