Will my car need mapping

[Keithlan1978]

Just bought another vxr on a 09 plate and I want to put a crossover delete an top hat on it but will they need mapping in or am I fine to run them without a remap? Thanks

It's one of those up in the air questions really. It'll generally run fine without mapping. But you'll always get those purists who say any adjustment to airflow or intake should at least be checked on a rolling road. A remap is pricey though and seems financially non viable for just a crossover delete and tophat.

I know I phoned rs tuning today and they’re around £480 for a remap, what are these companies like that come out to you and tune your car but obviously it doesn’t go on a rolling road?

Will be fine, I never remapped mine, ran perfectly well on CDTI kit, replacement hoses, tophat, Milltek turbo back etc

Again, another up in the air question lol. I'd only trust the well known vxr tuners. But in your position I'd definitely not bother for such a subtle mod.

Wouldn’t bother personally.

Wouldn’t bother with what mate?
