I've got a outside/inside temp gauge in the glove box thanks to the previous owner! but due to the cable length (it lives in there) is about as much use as a chocolate fire-guard.
Bar that it's all nuts & bolts and that does me fine!
Chipping can only be done on Bosch Edc controlled Auto's from 96my on,95 Auto's had the standard Bosch Ve mechanically governed injector pump.
So chipping is not an option on your car,but there are plenty of other things that can be done.(pump tweaks,larger intercoolers etc)
