Performance chips - do they really work?

[T_J_G]

hopefully i will be able to ell you when i get mine through.

not that i can drive my car at the moment though

Should be here Monday/Tuesday.

And how can i tell if it's a cheap resistor or the real deal!?

if you have to open up your ECU and fit a 'piggyback' chip then you know its the real deal.  The resistor mod requires you to splice a resistor into the inlet air temp sender wiring!

That one definately isn't a resistor style one.  It will replace a chip inside your ecu that looks the same and contains the fuelling map for your car.
