Well that is my top price I could stretch but aside from price it has remap and question is what other parts needs to be changed and if they need to be upgraded so the engine can cope with extra bhp without wear and break.
thanks for your time.
I realise that it is basically bug but nicely converted to blog so a bit over priced but did not see anything nicer for 4000 on ebay yet
Also what is your thought on having a huge rear wing but no front split as i can be dangerous for front to lift when at speed,
