Need Help: logging weirdness
Hey guys, I was looking for a little assistance here. I got some time on a dyno today to get my car tuned, and I am a little confused with my logs. All the values are seeming very sporadic. I have been poking around at other people's logs and they seem allot smoother; there are a couple of points in the logs where the RPM's even go appear to dip slightly and my wideband is all over the place. the dyno's wideband (tailpipe sniffer) was also reading completely different than mine, and it did not pick up on that super lean spot (which just so happens to correspond with one of those RPM's going backwards moment in the log...) I am running an RTEK 2.1 with a tungsten e2 on what I believe is the latest version of pocket logger (need to confirm). I was wondering if anyone had seen this before or has any ideas on what is going on here, any feedback would be much appreciated as I am not sure how much I trust the logging of the RTEK now.
On a positive note I was able to make right under 300 WHP (298) at 11 PSI. Looking to see how far I can push this RTEK setup safely...
Car mods are below if anyone is interested.
88 TII
Street ported motor (~20K mi)
All emissions / rats nest / PS / AC removed
Walbro 255
720 Pri/1000 Sec
Aeromotive A1000 FPR
-6AN SS fuel lines connected to the hard lines
MSD Digital 6A
Custom FMIC setup
3" Turbo back exhaust with Flowmaster super 44 muffler
Hybrid S5 turbo with Garrett T4 .70 A/R housing, ported wastegate
SS turbo oil feed line
ACT Street light flywheel & stage 3 clutch
Polyurethane mounts
TEIN RA coilovers
Koyo radiator
HKS SSQV BOV
Retk7 2.1
AEM Wideband
Greddy Profec B Spec II Boost Controller
GM 120 amp alternator
SS Clutch line
and some others...

Thanks for the reply. Unfortunately I do have the sensor down stream (behind the transmission), and it only has around 1.5 - 2k miles on it.
That being said, I am seeing sporadic logging with every sensor I am logging; if you take a good look at the attached logs you will see places in the RPM range during a 4th gear pull that the RPM's get lower for 1 logging interval, then jump up again. This does not seem right to me, and I have not seen this in any of the other logs I have looked at that other people have posted.
