How much fatter? [edit]The title should say...How much leaner?
Here's my dyno chart from the last tuning session, one for NA, & the other juice:
Please notice that the a/f ratio on the juice run was 11:1, which is on the fat side. This was with the 52/31 combo. I have since swapped the 31 fuel jet with the 28 (which I believe is the next size down???). First of all, is that safe to do without getting on the wideband? And secondly, how much leaner did I make it? Anybody know? <img src="https://ls1tech.com/threads/images/graemlins/confused.gif" alt="" />

Re: How much fatter? 31 for a 100 shot is a little rich IMOP. I was running a 31 fuel jet with my 125 shot and 28 with the 100 shot.
I run a 35 with my 150 62/35 but NX chart says 62/33, I found car likes the 35 fuel. Havent been to a dyno yet on the n20 or motor.
If your unsure just use the next size up in jet from what it recomends. The chart is in the safe zone that comes with the kit and you choose to tune if you wish from there.
Hope this helps.
