Message My car, a 94 TT, has nearly 70k miles on it and I recently had
to replace one of the injectors that completely failed. Shortly
after, it started idling rough, shaking a bit now and then, and
power seems to cut back dramatically as soon as I hit about
5,000 RPM under WOT. So it's fairly likely that I have more to
replace than just the one.

My long-term goals are to produce higher boost (and I do
currently via JWT chip and boost jets), but aim for better
safety margins and slightly higher than what stock injectors
will permit. I will never exceed 500 RWHP in this car.

While I am doing the upgrade, what things should I consider
servicing/replacing along the way?

My initial list:
CZP 550cc ECU (Federal 91 Octane)

JECS 550cc injectors + adapter kit (300 Degree or ?)
- will these be the newer pintle-less?

Fuel dampener? (OEM or aftermarket?)

Fuel pressure regulator? (OEM or aftermarket?)

Fuel lines? (hard kit or standard?)

Any advice is greatly appreciated.

Thanks!
