Hi,
i currently have a R33 GTS25T with light mods, it has full jasma exhaust, air filter, oil catch tank, aftermarket intercooler. Its currently running 11psi atm and producing about 183kw at the wheels. after about a week of hard driving the performance of the car has significantly gone down, any ideas of what the problem can be?i am currently getting it serviced and thinking of getting it dyno tuned again. Would getting it dyno tuned help?
And i have about 1500 to spend on the car, what would be the best mods to get for maximum horsepower.
