The short-
Before, trans shifted like mush, boost did not build past ~5 psi
The Long -
87 WE4 that had sat a lot for almost 3 years.
Trans was super mushy at the shift (sapping all power?). Somewhat resigned to replacement. Car is basically stock (best I knew). Boost gauge only showed about 5 psi max under WOT. (This is odd)
So after reading various forums embark on maintenance and some others items
A/C retrofit to R-134a
All new coolant/heater hoses, thermostat, cap, and coolant
New vacuum hoses
New vacuum block gasket
New EGR and gasket (stock)
New PCV, hose, and gasket (stock)
new fuel Filter (stock)
New plugs (stock)
New wires (stock)
New 02 sensor (stock)
Discover big intake manifold leak (maybe important)
New intake manifold gaskets
Discover #5 injector leaking
Make big change, go to 57#s with Extender chip (already of LT1 MAF and Translator)
Install AFPR, set static fuel pressure to 45psi (per chip instructions)
Go to install Fuel Pump Hot-wire, already had one (who knew?)
Notice the waste gaste "shaft" is threaded, I think this aftermarket adjustable style
Hook up Turbolink 4.0 (not that I understand it all)
Idle TPS 0.45 V
Idle IAC counts (closed loop, at temp) 30
Decide not to make any changes
Drive car for first time with all these changes. What a difference. Transmission shifts cleanly, boost builds to >15 psi, and low and behold AUDIBLE knock at WOT. Oops. But I view that as good, just need to keep finding and fixing the weak link.
The mystery to me, what affected the transmission that could have been improved shifting so much? That and boost?
Vacuum leaks are bad for boost, that I understand, but the transmission shifting.... Don't see the connection.
A bit more rambling-
Also, now, I have to chase the pegged BLM issue, reading threads on that other forum, have to hunt down more leaks I guess. Check valves, anyone have part number, cost, and where on the engine?
That and I must study what ALL Turbolink can tell me from a stoplight WOT blast. Oooh audible knock is scary. Need to put in the Caspers sensor so I don't listen for knock. Boosting the octane is once concern, here in LA 91 is highest most commonly found, chip is for 93. Need to find unleaded race fuel, or go the rocket fuel route, this was in the plan.
Appreciate any input.
