Hi i have a megane RS250. The previous owner did some modifications on it. Lowered suspension, bigger boost , chipped or mapped and changed the exhaust i think. I have a lot of wheel spin on second and third gear. The tyres i have are pirelli p zero nero gt 225/40/18. Tyres are relevantly new produced 2018 and they have like 90% wear. What can i do to fix this. Should i buy better tyres or do a new map. I feel a lot of turbo lag.
