15 6.4 gen3 Whipple ID1300 on E90 help tuning

[scatpack]

I have a 15 challenger 6spd I had the 2.9l gen2 Whipple and now switched to the gen3 ID1300 and 102mm Throttlebody on E90 and a killer chiller also switched to 3bar map. It starts and runs but afr at idle is at 20 so running really lean. Looking for help to dial this thing in

post all your info. Gen 2 tune, the new Gen 3 tune, and a log. We can go from there. Sounds very much like you didn't adjust your stoich for e90 and are commanding gasoline stoich.

I don't have a tune yet for the gen3 or the e90 this is all I have right now for my old tune for the gen2 on e85
