2023 Supra Manual: From Stock to Fully Modified!" 

amazing work, fantastic job. Another Whifbitz gem. well done to Paul and the guys 👍

Not a bad little increase :) I'm hoping to get a MK5 eventually. I get that with a high horsepower tune you need that downpipe and cat removal and so on. Correct me if I am wrong but I think 450ish is around the limit with a stock car with the cat in place (stage 1). Are there no other options for this such as a high flow cat to allow you to boost higher than stock whilst still being 'legal'? Maybe I am just at that time in life where I want a powerful fun car again but I am past having to put back on the stock bits every year for an MOT so it passes emissions. great work and lovely car!

Nice job gents!

No fueling mods? Stock clutch?
