At what point should you get an ECU tune?
Here's my plan.
First upgrade cooling with HE, CM30 pump, maybe phenolic spacers 1st.
Second upgrade intake with filters and maybe tubes. Maybe I'll do it the same time as cooling.
Third, upgrade pulley which I know needs an ECU tune to be effective.
Last, exhaust with short headers, maybe X-pipe and resonator delete.
Do I need an ECU tune after steps one and two? Do I need another ECU tune after the exhaust install again?
Just trying to plan my upgrades with so many ECU tunes. Thanks in advance.

apologies to OP for hijacking his thread, but always wanted to ask .... late better than never, you've all been there guys .... here it comes ... what are resonators and why do we delete them .. and also what are cats and what do we do with them ?

Definitely needed on the third to get the full benefit of the pulley. Also needed on the fourth to get the full benefit of the increased airflow.
Depending on the amount of time between the third and fourth upgrade you could wait and just get the ECU tune after the fourth and final upgrade.
Good luck! Have fun!

No need for an ECU tune with either of the first two upgrades.

The first two upgrades on your list don't require any ECU changes. However, pulley and headers do require changes to take full advantage of the increased boost and airflow.
