First off just wanted to say that Chris @ DC Performance helped out a lot with my car. I drove about 2 hours just to get my car tuned by him. And when I needed help getting my car ready to bring it to him he might not have answered (busy at work) but he would call me back same day.
1989 240sx hatch
Mods:
S13 blacktop Sr20det w/NISTune
Forced Performance 20g w/HKS actuator @ 12.5 lbs
STI 540 cc injectors
Z32 MAF
FMIC
Stock exhaust with 3" cutoff (tuned through stock exhaust)
Freddy intake manifold
Aftermarket exhaust manifold
255 walbro fuel pump (going bad [more on that later])
HKS SSQV
Stock internals
Dyno Tune via NISTune:

Chris spent a LOT of time on my car mainly because there was quite a few things wrong. My IACV was stuck, TPS was bad. We turned up the boost to 17 lbs, but found out soon enough that my fuel pump/fuel system wasn't up to par. It started losing pressure in the top end, even with a different adjustable FPR. With it running a tad lean in the top end it still produced 268 hp.
OVERALL I was very happy with the tuning, my car feels MUCH more responsive with no flat spots, and I got some bad ass MPG's on the way back from his shop. Used 1/4 tank of gas and drove from his shop to Bakersfield. Just wish I would've fixed the fuel problems before I got there. Will definitely be going back once all of my kinks are worked out, and I have some internal work done.
Recommend highly for anyone with NISTune (he has tuner license so you don't have to bring your own laptop/software), or any standalone.
