FWIW, when I started adding Techron to my tank, my fuel gauge started reading crazy. It took about 5 tanks to get the gauge working right again. Maybe unrelated, but that stuff isn't going in my tank again.

Very interesting. I never had that issue. :confused:

Guys I installed the Black Bettys grounding kit on my 370z today. This kit blows away the Stillen. The kit has TB ground wires, after install I went out to drive around and kicked it up pretty good and I know have a much better throttle response then before.

Now I only have 780miles so far, but I did have lack of throttle response right off the dealer lot with only 22miles on her.

I would check this out:: Go to myg37.com so a search for Black Betty's custom grounding kits:

I also run Shell Gas 93.. Seems like grounding out the TB helped big time :-)

Sorry Link wont work..

I think the verdict on grounding kits is still up in the air. Unless your car wasnt being provided and good path for the electricity I dont see how a better grounding kit will help. Now if you have added things like alot of stereo and things of that nature then it might help but I think stock the stock kit should be good. Are you sure it isnt just a preceived gain?

Well, you have look at the stock G-wires. They don't ground out the TB like this kit does. I installed this kit for looks really, I did not really think to get anything out of it, but it did help with throttle respones.

well Im all for better throttle response, might have to do that one one day.

The Stillen kit works fine to Ground out the TB's...It's just the instructions that are a little fuzzy. I noticed no difference in throttle response..

I'm sorry but you don't have that connected right. The Kit that I have runs the wires from the TB directly to the the battery.

The Stillen kit was not designed to do that.

I have a 370z Stillen kit and it's not setup the same as the Black Bettys kit.

No connected right? Huh?? Perhaps you do not understand the nature of grounds and ground systems. Not everything needs to run to the battery since it is grounded to the chassis. Any connection to the chassis is a connection to ground. Anybody can make a ground kit up with about $30 worth of wire and ends. This is not rocket science.

Yeah, seems somebody's butt dyno is reading rather optimistically.

Not rocket science; in fact, grounding systems are one big fat con-job. But they look nice! I imagine on a 20-yr old car that was driven in the snow belt, you might get an improvement if you scrape off some oxidation.

There are points on the eng that help when grounded. If you want to make up your own wires be my guess.. But like you said you want gain anything. I guess not when you just have wires running all over the eng. :rolleyes:

If you guys want some help on throttle response get the Black Bettys kit.
