Is my car broken or is it just me? Eurocharged s2 tune, catless dp, blackboost intakes. 9.1 60-130 was best I could do. Am I expecting to much from it? I thought it's suppose to be in the mid 8s on 93? I always feel a stumble or a loss of boost around the 100mph range, at times my boost gauge(banks gauge) that's connected to the obd sees 10psi, than eventually will climb back up. Plugs are new, oem plugs gapped down to 0.022,iat around 77-87 during the run.
Have you replace the check valve in the back of the engine? Are the wastegates fluttering. Ten minutes to check. Plenty of diagnostics in these threads.
Curious the logs - wastegate duty, boost, timing, iat
- is your IC pump dead or dying
- wastegate as mentioned above
- log that sucker and see what's cooking
- bad fuel?
- loss of boost - as mentioned / many threads in sticky
- you mentioned plugs are new - how about coils? You don't need a CEL to indicate a bad coil, many threads on this
you'll find it. You should be in high 7, low 8's

Yes checked that check valve, was still good and intact. Also replaced the pipe ontop of the intake manifold that has the 2 check valves, I beleive it's a brake booster line.

Coils were replaced at 19,000 miles, car has 38,000 now.
Ic pump works, I verified it turns on with diagnostic tool, also can see the coolant moving/cycling in the intercooler tank.
What is recommended for logging that's not to expensive?

I change my coils every 10k miles fwiw, have seen a few members convinced they were good and were running slow then got new ones and were running strong again
ultimately you'll need to log this, hptuners and several others discussed in the sticky, see below
Looks like your IC temps were fine on the pull. So can't be IC the pump.
Few things comes to my mind what can be problem:
1. Looks like you have Renntech Bow. Are you sure that thing is not leaking???
2. Not so common but faulty boost solenoid might cause problem.
3. Plugs. If you have OEM plugs no need to gap them anywhere on your tune level. Keep stock gap. I think this can't be the problem, but try stock cap. Could a little better and no hassle to gaping.
And yes with your Mods you should run about 7.5 - 8.1 range on pump gas. Depends on conditions.Weather, DA, slope.
For reference here is my M278 engine CLS500 Shooting Brake with M157 turbos and supporting mods. Pump gas custom dyno tune.

AND perfect conditions on that run.
I removed the blow off valve as I was suspecting it was at fault, so currently I am back to the original setup. I just ordered a set of Bosch coils as mine do have close to 20,000 miles on them, I did take it on multiple 3500 miles round trip drives, running it for 10-11hrs straight
Pulled the autul scanner out and dug around. No cel or anything on the dash.
But fuel pump short?? Also I do have a spool ethonal sensor installed in the engine bay, not sure if that is contributing to the low rail pressure number that's in red or if the actually pump itself is going bad.

are you running more than e50? What's your sensor reading for e content? At high demand (highway pulls) it's not keeping up with engine demand - too high of e content can be and issue or you need new fuel pumps to achieve this

Nop, straight 93 from gas station in schumburg. Fuel sensor is reading e10, which is what straight gas is I beleive.
can you take it to stock ecu settings and see if the code returns along with the poor performance?
Unfortunately I never received a handheld tune loader in my purchase a few years ago as eurocharged went through a ****ty service period with one of their investors.

Directly from their laptop at the shop in Elk grove village.
ah ok; call them and see if they'd upload your stock file - you never know; not to mention it'll be nice to have both files and a handheld moving forward into ownership and when you sell the car

Yes that's the plan. Appointment set for this Thursday.
