Mine's a cyberdyne electric gage too. I think I still have my mechanical gage around. I'll have to swap it in and find out. So you cleaned both the terminal at the pressure transducer (electrical connection) and cleaned up inside the transducer before reinstalling it on the fuel rail? I...

I've got an issue with erratic fuel pressure. I've got a walbro 340, adjustable pressure reg, electric gage. at idle I can set it with vac line off at 42 psi, then off and on with the line a few times and I can get it to read anywhere from 38 to 48 psi. When I'm driving around I've seen it go...

Stock Turbo. Running straight E85 w/ TT E85 6.0 chip.

Been troubleshooting an issue where the car will surge up and down at mid boost, (10 PSI or so). If I hold the throttle in this boost range it's very noticable, not as much when at WOT and just go across this zone, but my AFR is real erratic 'til I get into 2nd gear at WOT. Just installed...

I'm having some surging issue's at mid boost part throttle. I pulled off the down pipe and inspected the waste gate (best I could) and the plate is loose on the shaft. Is that normal? Looks like it closes all the way best I can tell, but noticed the plate was actually free to move around a...

I PM'd you.

Will this work/mount with stock turbo? Not familiar with the "1011-144" is that mfg part number? More info if you have that, I'm interested.

Having an issue where I get some surging while part throttle under boost at about 8 to 11 psi. WOT you don't really notice it but if you look at my powerlogger scan there's a bit of it going on. When holding part throttle it will boost will be up and down and few PSI, MAF up and down too. I...

Just got TurboTweak 6.0 chip in, running straight E85. So far so good. Can run 20 psi no knock. Got some surging issues that I'm thinking are related to my turbo, but so far so good.

Anyone running the Turbo Tweak 6.0 and closing the loop with an LC1 wideband? Is it working well? Does it hit the AFR setpoint pretty well? Any issues? Sounds like the way to go from what I read on TurboTweak site. I have an LCI and Powerlogger with 60lb injectors and TurboTweak chip that I...

I routed mine over the top of the tranny, then up through the floor next to the shifter cable up under the console. Worked out prett good. The LCI is mounted inside the frame rail passenger side.

Got my WideBand O2 in, and I get a major lean spike pretty close to the shift b/n 1st and 2nd. You can actually feel the car stop pulling when the O2's go up to 20 or so. It's probably like that for maybe a full second. Then back to normal and pulling hard. Seems like this is apparent only...

Thank you sir. As strange as it may seem I don't spend much time at the auto parts store. The only car I work on is the GN, and that ain't too often anymore..... Thanks again.

Who's 'they' and what's the 'Help!' section? Not sure what vendor you're referring to. Thanks again. Let me know.

I'll double check tomorrow, but sure measures up to me to be a shoulder bolt w/ M10 x 1.5 thread, 12mm diameter shoulder, 50mm shoulder length. Looks like I can get them from McMaster Carr #92981A407, $4.11 each. Should work. I'll double check the threadform at work tomorrow where I can do a...

I pulled the downpipe and one of the bolts that attaches the downpipe to the turbo housing was a bear coming off, and a couple threads are sheared off. Anyway its a stock downpipe and stock turbo, and I'm looking for new bolt/bolts. Anyone know if I can get these from GM, if so what's the part...

New injectors (60# from Full Throttle Speed) and Chip (Turbo Tweak), are in. Car runs great. Can run 15 psi w/o knock on 92 octane. Have an Innovate LC-1 wideband ready to installl. When I get that in, and everything tuned, I'll be adding some E85. I'll keep everyone posted.

Can you make a recommendation for me on new injectors and chip. Check out my sig. I don't really plan on upgrading the turbo, but I do want to get this car to run 16-18 psi of boost w/ 92 octane. I don't race it a lot, but may hit the track again someday. I'd like to get in the 12.5 sec range...

Thanks. I'll be putting in my spark translator and give it a try. I'll likely end up getting a new chip but I've got the spark translator there so I'll have to get that wired up and try it out. Thanks again.

I've had some feedback that the stock chip has 24 degrees timing and that is too much for 92 octane. Thoughts? I've never been able to push more than 10 psi without getting some knock on 92 or 93 octane. Put in higher octane and I can push about 17 psi, so I know it's not false knock. O2's...
