Always happy to help a fellow Scooby fanatic. One bit of advice is do the research save for as long as you can and do as much as you can with one remap. Don't fit some bits and remap due to funds and then save up and fit more then get another remap. I know it is so tempting to buy a couple if bits then get a remap as quickly as possible to get the power gains but you end up regretting it and wish you had just saved that bit longer.
Everyone has different opinions when it comes to modding but just keep an open mind and you will be fine
