Probably the cheapest and most far ranging mod I've had done is to up the fuel pressure from the stock regulator setting of 40 psi to 60 or more.
It doesn't change anything but provides for a bit more richer mix throughout the entire mapping range which is what these babies need as they are mapped lean. I also believe that it provides a better spray pattern from the injectors.
It is much better behaved with absolutely no snatching off idle and just sings. MPG is still in the 48-56 MPG range depending on what I'm doing. Will also power the front off in 1st,2nd+3rd.
This is easily done by modifying the existing fuel pressure regulator or if you have a nice dealer he should give you one as he should have some recalled ones laying around. They might be a bit noisy but they work fine.
I'm working on a tech set of photos to share. But all that is necessary is to use a set of fitting sockets and squeeze the regulator spring hat to put more preload on the regulator spring. My dealer who recommended this had the whole thing done in about 15 min. and charged me $20. for labor but he did something else too at the time.
Though I don't recommend the hi flow air filters if you do put one on especially with a can you will need the extra fuel that the stock maps still won't provide as they are still on the lean side. This can be proven with the use of a TuneBoy/TuneEdit.
