Customer contacted me saying he'd had full CS software done by another coder but it didn't feel right. And the gearbox wasn't behaving like what CS software should.

Connected to the car and read the files. Car was still fully stock bar the gearbox software, it had CSL software on it instead.

He asked me to redo the car for him in CS and leave the suspension stock.

Be careful who you choose to do work on your pride and joy. There's alot of amateur coders, new starters or even long established coders that have basic knowledge of these cars, cut corners or don't do the work properly.

The coder is now blanking his messages after he's asking for a refund. Angers me that people like this are taking money from people and not doing the work right.

The customers made up with the car now, night and day difference.
