Not sure how to feel about this. A company on Facebook have confirmed to me that they can get crackles out of the PFL S3 as they have the available software. They say not a lot of people have the software in the UK. They've proposed £350 for a stage 1 remap including crackles and dyno. Figures of 350bhp with a 30% torque increase. They've got good reviews online, however very recent. They've managed to get crackles out of all sorts of different cars. As this is unheard of to me, naturally my instinct is to think this is all too good to be true? If any members want to PM and see if I can source more info I will be happy to do so. If all promised is true I can imagine a lot of happy PFL owners. Not naming the company as I'm not shaming, just interested in hearing thoughts to be had from other forum members.
