Good to know. I am still on the stock trans with with similar boost on pump gas and water/meth. I have to avoid 30+ PSI 5-6 shifts as this can cause soft "flaired" shifts which is torque induced clutch pack slippage. Therefore I need to do what you just did. I am impressed at the torque these ZF...

Super impressive to take on this job and you documented it! How was the stock trans performing before the rebuild and at what torque?

Maybe this will help someone in the future. Cruising down the road a serious misfire started and got a service engine light. Code was 112601 Injector 6 activation line break. Torque limitation "limp" code 10D000 was also present. Data log indicated a/f lean at 19. I tried another o2 sensor with...

Brian is at the top of my list but he is not taking on transmission builds until after TX2K. Assuming I get the trans out before then I may just send it to Pure as they claim to have really quick turnaround times currently.

It's time to pull my trans and ship it out for rebuild. Pure seems to be the most popular then Jack's and Brian @ Applied Torque Solutions. From what I can tell C and E hubs should be replaced with upgraded units. Of course increased clutch counts are standard. Pure claims to have a proprietary...

Tune revision for less torque down low. Do you have xhp in drag raced mode and line pressure increase turned on?

Just keep driving and my guess is there are 68 to 70 more drops of diff lube to weep out before its happy.

Oh the kids today... Lol modern traction control is great, but there was a time before traction control, you got to be in control of your car.

Easy to make a faraday cage, take any conductive metal enclosure and connect to ground. As easy as that is I don't do it.

At least I drive mine.

Look around, there are normally some people that have the kit and don't use the TB adapter.

The Titan kit is a snow performance kit with the supra reservoir/pump bracket and throttle body adapter. You can fabricate a bracket, plumb the nozzle into your aftermarket charge pipe bung, and pickup the boost reference somewhere on the manifold. The Titan kit just makes things easier for...

I agree with @Thraxbert if you insist on running E50 on an upgraded turbo, but the simple and cheaper version is to drop back to E30 at max and stick with your stock fuel system and trans. I would also caution you that I know of two CTS turbos that failed when they were first released. I have...

I don't recommend going past what the factory HPFP can handle. With the CTS turbo, catted DP, and EOS manifold, and water/meth my setup did 560whp on 92 octane @25-26 psi. BTW there is a thread with a title something like: "101 Routes to big power" that has all the info you are looking for.

All you need is the turbo and a E30 tune, maybe a flex fuel sensor to make life easy. You will run out of HPFP on the upgraded turbo and E50. Plus the power you will make on a CTS and E50 is more than the trans can handle, I already ran that experiment for you.

I have one and no cel.

I thought the stock turbo was fine on pump gas until I tried a bigger turbo (CTS). Even at the same boost level, on pump gas, on factory fuel system the big turbo setup was way faster than stock turbo (560 rwhp on 92 and meth). The big turbo also gave that increasing with RPM power curve I love...

Driving in the snow and ice recently got me thinking about VSC aka traction control potentially causing this issue. After a drive on super slick snow/ice where VSC is modulating torque significantly, try driving onto a surface with good grip. It takes VSC a little while to "learn" that there is...

Question for all the people experiencing this issue, does it happen with VSC off? Basically is the stability control system pulling torque then ramping it back to normal?
