I'm just referring to my (14 ctsv) car, but out of the many tunes i've seen for the Vs 99% of them have the enrichment rate set around .5 or higher (stock is .02). Anytime I have set mine at that quick of a rate the commanded fuel switches instantly but there is a lag of when the fuel actually comes down to that point causing a huge "lean" condition during that transition. Isn't it pretty pointless to set such a quick enrichment rate if all that it's going to do is cause a huge lean condition??
