For your 1st stage remap were you provided with any torque and bhp comparison charts. I would be interested to see the differences.
SM remapping is the name of the company, i can't remember the software name. You can find him on fb and ask for the software name.
So it is the 1.4 multiair. The reason i choose this guy over other offers: he is mobile, he came to my address, and he is offering interest free finance. The total cost was £180, i paid £45 on the day and the rest in 3 monthly instalments.
In terms of service provided, well..he took a read of the ecu with his machine and send it to the company which creates the software. It took around 30min for them to get back.
More time consuming was the reading takings and the software run back on the ecu.
He fixed a faulty sensor with the start/stop system, he left the car with no issues/ faults.
About performance...it is noticeable that the car works smoother, less gear changing than before and as i have wrote in sport mode is really good.
BHP is at 170 minimum with this software, this is what I was told and in sport mode reminds me the A4 avant i use to drive in 2015 with 177bhp.
The air filter is suppose to be part of stage 2. I am still looking for options about it but i am not sure if i will do it.
I hope this helps.
