Hey guys, I posted this in the FI section and realized it's better suited for the Engine Management section. Here's what's going on, I have an InlinePro Stage 1 Kit. I'm running an identical set up with my friends 01 (I have an 02). The only difference between our set up was the exhaust, fuel pump and map sensor. I've calibrated my map for the 4 Bar Hondata, he has an SOS 3 Bar. I'm leaning out during idle and it's sputtering when I give it a bit of gas.

Prior to install, I was NA and my motor was running beautifully.

Here's my original thread. Any additional input would be greatly appreciated!
