If you already had a full exhaust and added G3's..

Would/did anyone get a tune after just the gen3? Or would it be better to wait until you got more mods?

It would be a waste of money to get a tune with just intakes... this car seems to respond very well to mods. I am going to get all the NA power mods and then get the car tuned myself. It's not cheap to get a tune so I want to make it count.

This is what I'm doing as well.

Intake - Needed (Have K&N's and MAF tubes right now, waiting for full intake)
Pulleys - Check
Oil Cooler - Check
Headers - Check
Exhaust - Check

Last mod needed before tune.

Yeah, I need to get an oil cooler, but since I don't track the car, i'm not going to worry to much about it right now... just getting on the car here and there is fine for me... when I can afford it i'll go with the Z1 25 row cooler.

In my opinion as well as others, I would get the car tuned after installing G3 intakes. When I had my car tuned, the stock tune with G3s would run leaner than I am comfortable with and there was also some detonation which is something others have experienced as well.

After the tune, my A/F ratio was nice and safe across the board, the car ran smoother and I picked up another 5whp.

This is what I thought as well but I had concerns with what Christian370z said below...

Thats what my plan was as well.

This was my main concern will the engine be safe as a daily driver with the G3's and no tune until I get the other mods mentioned about and tune it which could be months???

Who has had any issues or detontation running the G3's with no tune?

How long have most of you guys been riding your Z's with G3's and no tune?

It should be ok. I know a lot of people on here don't get a tune until they have an intake, exhaust, and HFC/Test Pipe. That's my plan, got the first 2 done and just need the last before I get tuned. Haven't had any issues yet.

I drove mine without a tune for a couple of weeks. The first pull on the dyno, both my tuner (Seb at SpecialtyZ) and I could hear/feel some detonation especially when looking at the A/F and power curves. I feel that everyone should get a tune after installing G3s, but I did it because I wanted to have 100% confidence in my car and having the chance of losing an engine over a couple hundred dollar tune seemed a bit silly.


I also gained at peak 5whp/14ftlbs after the tune, but I gained so much more under the curve especially with torque.
