I seem to have found some useful information, but its freezing outside and I don't have the resources here at home to check the TPS Shaft Seals for a leak, but I've felt around and tightened couplers around my FMIC setup.

Problem:

I just installed a PTE60-1 on my 2.3 1G and had a friend tune it at 20psi. Yesterday, I was boosting around and seemed to have develope a leak. Now, when I try to smash it in 2nd or 3rd gear - I hit about 3-4psi (and it pulls accordingly) and it continues to spool up to 20psi, but with NO power in return.

My gauge reads 20 everytime. I logged all params. and did a few pulls, and it seems that while I'm still pressing the pedal down to WOT, Link shows the TPS at 100% until it starts to feel like its losing power -- at which point the Link shows the TPS dropping off in large % increments.

I checked the difference in raw airflow of pulls I did shortly before this was happening and compared it to the same gear / mph and rpm of when this problem popped up:

Before - 4400rpms / 58mph / 1557hz (RAWairflow) / InjDuty 60% / TPS 97%

After - 4400rpms / 58mph / 1931 hz (RAWairflow) / InjDuty 70% / TPS 88%

There you have it. Any help is appreciated. If I left out any useful information, let me know. I'd like to get her to the track with the new setup soon!

Thanks!
 
I'm not receiving any knock, and my wideband o2 isn't installed (yet). (prepares for definite flaming).

I can't post the logs, but if you're looking to help me out I'd gladly send you the files for DSMLink via AIM or PM. Thanks agian guys! Boost leak testing it today. Also, I pulled the plugs - they were fouled up pretty bad, I replaced them - no change (not surprised).
