Bank Lean Question with intake only

[Chrisrokc]

I have both banks lean according to my ecu. I am running a TRAP intake only. Because of a friend I have a copy of HPtuners and can edit the ECU as needed. What do you recommend I do to correct this? Thanks!

Anyone?

You can tweak the MAF table to recalibrate for the additional air. Bump the numbers up by a few percent, see how it does, and tweak from there...

First make sure you do not have a leak between the maf and throttle body, if all is good then do a scan and check your long term fuel trims.
Most likely with the trap they are running quite high on the positive side, 14-20. If so mutiply your entire maf table by 1.10 to start.

Hey thanks guys for the help. I will log some and see what it is showing then change it as instructed. Today the light went off so who knows. I don't have a leak that I know of, just checked, but who knows. I remember reading when i bought this a long time ago and this was happening to others.

Anyways thanks again!
