What upgrades will require me to have to tune my car 1994 300zx tt

Welcome to NICO!

I'm not sure I understand your question. Tuning a car isn't dependent on upgrades.
Do you mean "What upgrades I make on a car will require a re-tune to run correctly"?

Things like changing injectors for higher flowing ones, cams/or cam gears, or aftermarket ECU installs will require a tune.

i was wanting to upgrade my exhaust system and someone told me if i did i would need it retuned is that true

Whoever told you that must drive a subbie or a DSM and know nothing about z32s

No you don't need a re-tune for an upgraded exhaust.

Welcome to NICO!!! There are tons of things that will require a retune on a Z32, exhaust is not one of them.

Thanks and yes he has an sti

Wow Anton nailed it haha.

I bet it was funny seeing people upgrade their exhaust then complain about how their car ran like crap. Did that happen often or did most subby owners know that they needed a retune with the exhaust? I'm just curious.

most seam to know, well at least I did.

Gotta love 90's Nissan ECCS system. Unless you really messed with stuff, the MAFS would see the extra air flow from bolt-on mods, and the ECU would simply compensate. So simple, but so effective.
