Where did you get spacer? I haven't seen a need for it yet. Do you have to change anything other than the injectors? Rail? Also, did you see an improvement?

It came from another YW member who had it custom made. The injectors were added as a result of a CEL which was a lean code, he said after he installed the injectors the code went away.

I installed both TB spacer and injectors at the same time so I can confirm nor deny if there was ever such a condition or if larger injectors solve it.

You don't have to change the rail, stock one works fine. Might want to pick up new injector seals depending on the condition of the ones that are on there currently. Less than $10 for all four, so it's worth it to be safe.

No dyno so no real numbers. Since I installed both a TB spacer and the injectors I can't honestly say which was responsible but it does feel like it pulls harder at WOT.

Gas mileage has not decreased, however at cold start you can smell the difference because of how rich it'll run when warming up.
