02 Cummins Problem

I just joined this forum after looking at it so much, I think I need a little help and insight from you guys, here's my problem. I have a 02 Cummins 3500 with 200,000 on it. When I bought it, it had a miss when it warmed up. At idle and when driving, I put new dap 100hp injectors in and a fass 95 3/8in fuel line(old style) and it ran perfect, everything else is stock but I have a 4inch turbo back exhaust, Now it idles good and starts first revolution always but when it drives it surges. Cold or hot. I am aware of the tps might be the problem. Sometimes if I hold my foot steadily on the gas it seems like it's not getting enough fuel and it's like I'm letting my foot off when I'm not. Also another weird thing I have not yet narrowed down is around 15-2000rpms it has a miss. It doesn't miss on level ground. Only when going down hill. Really bad the worse the hill. I have a feeling it might be the vp. I do not have a fuel gauge and haven't looked at it yet. It does white smoke a little on a cold start but blows black as normal. any advice or feed back would be greatly appreciated!

If you don't have a scanner cycle the key 3 times to show you the codes if there are any stored in the ecm. They should come up at the trip meter.

02 6 speed QCSB, leveled, cowl hood, 6000K HIDs, drag comp, DAP 7x.010 SAC sticks, SB 3250 dd clutch, 5in exhaust, AFE intake, Fass 150, glowshift (EGT,boost,FP), chrome 20x14 xd riots, 33x12.5x20 toyo m/t, follow me on instagram for truck pics @pr0ject_blue

I forgot to mention I have done that, before injectors and fass I had the 0216 death code which I had my suspicions and now since I've installed I have no codes. Its all clear. Is it possible the key trick is faulty?

Key trick does not always bring up codes. 1998-2000 are worse for this.

Try some stanadyne, lucas or dieselkleen for better lubrication. Might make things better.
