Gastester measures carbon monoxide the principal indicator of air fuel ratio and combustion efficiency. Use gastester to tune for performance or to pass a state mandated emissions test. The advantage is a digital readout that shows the level of carbon monoxide which can be translated into a air fuel ratio using the provided conversion table. So stop tuning by ear and start tuning your car, truck or motorcycle the professional way with an exhaust gas analyzer that's proven in 10 years of customer use. Just ask Ducati Richmond. Gastester works!
I've been selling Gunson tools since 1991 to motor sport enthusiasts like you that want to tune their rides for top performance. I use what I sell and can answer your technical questions about tuning and product selection. But don't ask my competitors tuning questions, they're order takers and not tuners.
I stock all Gunson products imported to the US. If I can't get it no one can.
Check the ads above. Four and five gas analyzers cost thousands of dollars and are overkill for the do-it-yourselfer. With Gastester you get nearly the same results as the expensive gas analyzers at a fraction of the cost. It's almost a no brain'r.
