Sean Roes A/F meter does double duty!!!

[bad viper]

I used Sean's A/F led display to fine tune the VEC when it was first installed. Great item! Lately, whenever I first do a half
throttle burst I noticed car lugged and A/F went to red(lean reading). this led me to believe the Fuel filter may be
partially clogged. Yep..full of black residue!!!Now meter
shows blue(rich).You can trust this product for accuracy.
