what should my next mods be?

[VIPERBLUELX]

I have done the following mods to my 91 GSX since I got it a few months ago:
upper IC pipe, HKS tb elbow, full 2.5" exhaust, aircan mod with K&N filter, big 16g, ported 02 housing, 2g exhaust manifold, 255lph fuel pump.

I'm wondering if a FMIC should be next, or GM maf meter, or what?

Boost gauge and mbc if you still don't have it. A AFPR for the 255 so it doesn't overrun your stock fpr. I would do maft, injectors and safc together. FMIC wouldn't hurt either.

I do have a boost gauge and mbc, those were the first mods. Who sells a good AFPR?

any good vendor will have a list of AFPRS to buy. i'd also go with an FMIC
