End of yearlong drama... back to 9psi

[JackoliciousLegs]

I recently decided that it'd be a HUGE hassle to port the wastegate on my daily driver, so it was not feasible with the open exhaust (or high flow cats) to set the boost above 5.5psi for fear of creeping to certain doom.

Side note to keep in mind: I had just fixed my A/F issues.
Side note 2: When I bought the car, it wasn't boosting properly.

I was hesitant to set the car back to the way I got it because last night I reattached the stock EBC (Electronic Boost Controller for those nonboosted folk) and it wouldn't work. It was still set at 5.5psi... not the 8.6784952 that it should be set at.

Well, today I had Murph toss on my old cats and fix the EGR pipe for a whopping $40. Then I bought a new 02 sensor.

Side note 3: My A/F gauge has never read below 14:1A/F even after I had it on petes wideband reading 10.2:!.
Side note 4: Turbo A/F ratios should be between 10 and 12.5...

Took it for a test drive, and WHAMO... 9psi slams hard and holds til redline. A/F gauge showing 10.5-11:1 A/F... MY PILE WORKS!!!!

For the first time EVER... I am at full boost... reading correct readings... with proper A/F ratios.

BWHAHAHAHAHA!! My first HPDE is right around the corner!!!

I knew something was wrong with the car at that time. It wasn't running 100%... I need a busted pile to drive on the side, but my signing bonus is right around the corner

haha... i was wrong. just drove it back to work... 5.5psi and fucking 14:1... time to go hunting again.

i dunno if its true for your RX, but on DSMs you cant trust an A/F with the stock o2 sensor, not at all accurate, hence the need for a wideband...but like I said dunno bout the RX? But anyway, you have an internal gate right????? could it be sticking open or wastegate actuator fucking up????? only allowing for 5.5 boost? sorry if it isnt even possible, just wanted to post something :wink:

I know the A/F is untrustable. I just had Pete's wideband in it. The A/F is ok. I'm worried about why it's boosting well sometimes and not others.
