You are correct, however I am not looking to add any more fuel - just retard the timing to help the turbo out a bit. I was looking to do this by pulling some timing out of the base SOI map, or by dropping the ICP to slow the SOC.

I do understand that by dropping the ICP you indirectly increase PW, which I dont think will have a great effect on the total quantity of fuel delivered - it just wont be as complete of a burn.

I have had a bit of time to play around with this the last few days and it seem to be working. It doesn't have that "neck snapping" crispness, but instead a smooth progressive feel.

Have not decided which I like more, but I do like the reduced engine noise.
