Surging, EGT's, and Power questions here.

[Cuda]

I am guessing at what is happening with some surge while driving anywhere from 45-60.. The rail pressure gauge stays pretty steady, but when it it happening, my EGT gauges is fluttering some going up and down about 200 deg. . I am thinking that a posible loose connection may have caused this, and the jerking of the truck was exposing it. Either way, I am disconnecting the pressure box, to give some drive time, then I may unload the smarty to see if any of this has an impact on it. We shall see.
The other question is that I changed the turbo to a S300 62-71-14, and went back to the local 1/8th mile.. Ran the same exact numbers as I did with the stock turbo, and I'm thinking to myself.. wtf? I know the butt dyno believes it pulls harder but man that was dissapointing. I may be out of fuel here but it seems that there are a lot of these same trucks making plenty of power with stock injectors. I do have a Fass95 and an Arson kit, but still wondering wtf is going on here with a lack of go. I am extending my fuel pressure gauge from under the hood to the cowl so I can watch for presure drop as well. Rail Pressure seems to maintain 19 to 20k.
Times were 8.7 @ 84 with a 2.0 60' ... Smarty TNT at sw7, tq4, timing 2. Also tried SW9 with no real noted change.

there will be some new software on the MADS site shortly too.

Thanks for the info Bob... and I will probably update, but, I don't believe the Smarty is the route cause of this since I have been running it for almost a year now without any problems.
On another note, I watched the rail pressure a few more times during some hard blasts down the road, and I have seen it drop to as low as 16k.. No good.
