Car Update...I'm getting closer...
...to getting it to run decently at WOT. Man its been a long road. Nearly 10K miles since the motor pull and all the damn work and I'm still working out kinks every week. Here's the latest:
1. Oil change, 7 1/2 qts. of Mobil OW-40 and Mobil Oil Filter.
2. Sent a sample of the oil to Blackstone Laboratories for a full analysis of its composition.
3. Finally received delivery of the Uber boost gauge from AWE Tuning:
Reads vacuum as well as boost to 30 psi. Completely bad-ass and needed for any diagnosis of trouble with forced induction motors. The thing about installation is that when the instructions say 2 hours, its safe to times that by 3. After nearly 5 hours of finagling, its in....looks great and works perfectly.
4. The problem is that after I romped on it during a 4th gear rip, I immediately realized, upon looking at the gauge, that the turbos are over-boosting...big time at that. At stage I, my old turbos at stock configuration spiked at 8 psi. At Stage II, the old turbos spiked at 15. At Stage II+, spiked at 16. At Stage III, they should spike at 21 and taper to 19. It spiked to 27 psi!!!!...then tripped the CEL (check engine light) and dumbed down the boost/air/fuel map to a 10 to 12 psi flutter. Very very bad. Immediately called my mechanic. He was dumb-founded..."you have super-turbos...they should not be able to do that..." and asked me to come in to do some work.
5. I downloaded the GIAC AWE TUNING Manual Boost Controller (MBC) software on my laptop and went into Dynospot to have them download a new adjustable tune from AWE in Pennsylvania. He decided to bring it down by 20% and I readily agreed. I took it for a spin and saw that the MBC surely DID reduce the boost spike to 23-24 psi, still quite high. The taper is now a nice 20 psi but that too has to get lowered.
6. Its like a checklist with the last issue being the boost flutter...flutters between 10-12 psi at part-throttle. I'll be logging and tracking that issue down next.
Anywayz, I'm off to do some camping this weekend with my goober friends...we're heading up to gorgeous Mendicino.
