WERD TO THAT x2 Chris
hehe
I am running a programmable dis2 with the e-manage. i amonly pulling out like 3 degrees at max boost max rpm.
In my opinion, the key is to get the mechanical FPR (SFMU) to do most of the fuel compensation. The key is to try to get a mechanically made fuel pressure curve to be as close to what you need and make minor adjustments with the piggyback. I am running like 15-17 psi fuel pressure at idle and am using a 6.5:1 disk with 440cc injectors. This is real close to the proper fuel i need. My emanage correction are no bigger than +- 10% this allows the timing to be minimally affected by correction. I think the biggest mistake people make when tuning is that the use the piggyback to pull out like 30 or 40% that is when timing gets all crazy.
