What fueling tables? Are you still using a MAF sensor? What are you using to datalog?

Sorry I uploaded it but don't know why it didn't attach. Yes I'm running a MAF and loging with datamaster and tunercat. I'll try to attach my mods when I get to my laptop. I'm trying to get rid of my split blm rich on left and lean on the right Thanks for responding

I checked for a intake leak with some starting fluid to c if the idel went up and it didn't if there is a better way let me know. As for exhaust leak a can't hear any. Injectors I don't know how to test to c if they are leaking
Smoke test is the only reliable way to find an intake leak. You can even use a smoke machine to find exhaust leaks too. How far apart are the BLMs? And your attachment is upside down.

Your split BLM are likely a direct result of your throttle body's physical characteristics and the design of the LT intakes. You need to drill a bleed hole through the front idle passage into the rear passage allowing for base idle air to pass through into the idle circuit instead of opening the throttle blades to allow idle air. The bypass allows you to close the blades and will reduce or eliminate the split in BLM. Study the stock TB to get a better idea of what I'm telling you.
A good test to see if this is the issue is if you hold the engine at 2000 rpm and the fuel trims are closer, then it likely isn't an O2 or air leak issue.

I have been working in the TB IAC counts would not come off 160 I'm up to a 7/32 hole now. IAC counts are down to 90 now but labtop went down so I use datamaster to view it but I will check the blms at 2000 rpms to see were they are at. Thanks for the information looks like I have a lot to look over thanks again
