I recently purchased an 87 TII S4 Im bringing it back to stock and the guy I bought it from has 1600cc secondary injectors. Would I be able to use these and my stock ecu? Or should I go back to the stock secondary injectors

If your returning it to stock ECU, you need to run stock injectors

It would perform ridiculously poor with a stock ECU and 1600cc secondaries. When the secondaries trigger, you would hit a wall and black smoke would pour out the exhaust.

Stock ECU - Stock injectors.

Okay thank you I have a Haltech E6K ECU but Im not sure if it works or not i need some way to test it and if it does work i will use that with the upgraded secondaries

The Haltech will stage those injectors just fine, but of course it will have to be tuned to use them.
