Pig

Hi All, I thought I would introduce myself. I have been in the supra world for a few years and currently run a 650bhp 6 speed Supra. I bought the car as I wanted a fun car to use daily as the supra is not a daily car anymore. I picked her up tonight and whilst she is great, I need more power and a little more noise. The car is totally standard apart from a K&N induction kit/filter (One of those plastic things). First few questions I need to know are: 1. When does the cam belt need changing? 2. What are the recommendations for a little more noise (not lots)? 3. More power.... In relation to more power, is there a way of remapping the ECU easily? After a little search, I have found RomRaider but not looked at in detail yet. I will do my own mapping but are there base maps available? What boost is ok to run without a decat and with a STD exhaust? Thanks Jon
