Don't need to save for real tuning. Got a 400bhp nissan 200sx for that.
Got 7k sitting in my bank account coz i am saving for a house, but just wanted to give it a little bit extra as i feel the car doesn't pick up well down low. it needs the arse ragged off it and to be kept above 5krpm to get anything out of it.
I don't want to keep ragging the arse to have fun, i would rather only drive up to 5.5-6krpm maximum as i want the car to be reliable.
High revs = more wear.
