Yeah sorry i don't know much about cars and this may not even be an issue but i am slightly concerned.
1. My engine temp gauge never quite reaches centre (90 degrees) it ALWAYS seems to run at 82-84 degrees no matter what the situation
2. I have a 53 plate 1.8 sri with pipercross induction and cat back SS exhaust, only seem to be getting about 28-30mpg, (driven hard at times yes, but at other times extremely leisurely).
A friend of mine said the two mods may be causing it to run a little rich but im not sure. If anyone could shed any light at all on either of these issues it would be very much appreciated!!
