I just filled up the first time after taking out the front exhaust baffle and fitting a stealth air cleaner.
Prior to baffle removal the last fill up was 147 miles with 21.5 litres giving 31 mpg.
Filled up this morning at 170 miles with 39 litres giving 19.8 mpg.
Seems a bit of a massive change!
Engine seems to run fine, possibly pops more on overrun than before, but I can't be certain.
Is that a typical figure, or should I start looking at other stuff? Lambda sensors maybe?
