[s-cars] Alternatives to RS2 Injectors - related Q

[otw185]

I forgot to mention I did indeed change to new timing
and boost chips created with this in mind when making
the injectors/cam change as well.  Still surprise to
see significant fuel economy improvement....

The talk of injectors has reminded me about an
observation of mine.

About a month ago I switched to 37#/hr. injectors and
somehow my (92's) computer is telling me I'm now
getting avg. MPG of about 21.5.  In the past with
stock injectors and RS2 turbo, I was seeing more like
about 17 all-around MPG.  All other factors are more
or less constant except I also switched out the
exhaust cam to a 7A type at the same time.

Any explanation for why I'm showing better fuel
economy given I should be burning more fuel with the
larger injectors -- or is it a calibration issue with
the Motronic ?  I haven't yet just calculated my
mileage by actual fuel volume used vs. miles which I
keep forgetting to do.
