Hi,

Just bought a Tunit V-PD box on eBay for my vrs, got it for

Could be wrong but a thing you have preset setting using a jumper. Think the dealer sets the jumper to a certain setting for a laptop tune so just use the other settings and you'll be ok.

I'd give the laptop setting a go. Dont think Tunit alter the boost pressure directly only fueling so it might be alright.

Give awesome Sarah a PM. They are tunint dealers.

I agree with above... don't think they alter boost pressure, so stick it on and see how you feel... it may overfuel yours a bit too much, if it smokes too much get it turned down, if not enjoy!

The 'proper' tuning boxes (Tunit\Dragon - not ebay resistors!) are good pieces of kit & well underrated I'd say start on the lowest setting & work your way up
