What can I use to correct lean tip in?
At any throttle setting, if I ease onto the gas, it temporarly goes lean (17-18) and hesitates
Thanks

Lots and Lots of things affect tip in... First off are the VE tables dialed in? MAF dialed in? Is injection timing dialed in? THEN most importantly what's fuel pressure? Then there's O2 cal, etc cal, transient fuel impact and general transient fuel cals... I just spent 2 days chasing my tail on one where right at 1000 rpms if you just barely touched the throttle it would do this because the fuel pressure regulator was set too low (48psi) for the sudden boost spike of a pd blower just to imphasize "it's" importance... Turned it up to 60 and the problem is 100% gone.
It would also be wise to list the modifications, the tune and a log
