Forget about the cable, it's really a bad tune, just take the car to Jez @ Horsham Dev and you'll have a perfect custom tune for your setup. You just need to add the cost of oil and coolant to this package and you're good to go
Also the price is awesome as you see it, can also promise you that if we manage to bring the kit here cheaper than that, we will refund you the difference!
PM me and let's discuss your requirments.
Thanks,
Adrian
