JLT Intake tune for GT350
Looking for guidance for GT350 JLT intake tune. Fuel trims are 29% and adding 30% to trinity stock tune modifier only changes it by 9%. Looking for MAF transfer or someone that knows the magic amount to add. Thanks

Wow, you've got big air leak issues man.. You need to check the air intake, headers/exhaust manifolds, and exhaust system itself.. not good... shouldn't be that lean at all...
check the air intake, make sure it's all fully connected/together, and that all clamps/bolts from air filter to throttle body are all TIGHT so no air leaks anywhere...
check the headers/exhaust manifolds and re-tighten all bolts, make sure all TIGHT so no air leaks.. make sure no cracked manifolds, gaskets all good...
check headers/exhaust manifolds connections to exhaust and the whole exhaust system itself, make sure all bolts/clamps are TIGHT so no air leaks anywhere...
Make sure all breather hoses and vacuum lines are all connected where they should be... make sure no cracked/split hoses...
Check around the intake manifold, make sure no air leaks around the intake manifold...
then, after everything is fixed and tightened up, you need to check a new steady driving log.....

Id start with JLT to see if they can provide a known curve for the CAI/MAF combo.
