looking for suggestions

[2543arvin]

im in the process of completing my na-t swap (just trying to get the stupid wiring harness, which is impossible to find) and im looking for suggestions on what to do next. any help would be appreciated. when the swap is done, my mods will include:

3.5" downpipe
2.5" cat back...i know it doesnt make sense, but i bought it that way
walbro 255 lph fuel pump
manual boost controller
24x12x3 FMIC
2.5" intercooler piping

ditch the 2.5in catback and get yourself a good 3in, 3.5in DP might be over kill unless you are using an upgraded CT at over 18PSI and you might want to look into a wide band 02 and some sort of piggy back
