[Official] "Do I need a tune with bolt-ons?" thread

[frost]

Please direct questions about tuning related to bolt-ons to this thread.

[boomboom]

Would I need to get it tuned after installing the gen111 intake, catback exhaust and new cats and oil cooler?

[Jamaica]

Yes please.

[G37sHKS]

Yeah, If you can afford a custom tune then go for it.

you wont get enough gains from these breathing mods until you custom tune your car.

Agreed if you want to get the rest out of your mods you will need a tune, You should be fine as far as AFR. But if you add another bolt-on like headers you will be off and your stock ECU will not be able to compensate.

So if I get headers get a tune, or get a tune even though I am not getting headers?

You can get full bolt-ons with out headers, and get a tune right after that. Or you can get full bolt-ons including headers then get the tune. Personally, I wouldn't get the headers. Waste of money, imo.

**** man, I tune my cars in stock format ;-)

All vehicles can beneift from changing the factory mapping with or with out mods.

Your car will compensate very well up to a point, but a tune should make it perfect, if your tuner is decent.

Having said that I would not loose sleep over it, get the tune when you are satisifed with your mods. N/A motors are more forgiving.

Awesome, thank you..no i don't plan on headers, cats are better imo

[onefastz]

I know this has probably been asked before, but I've got the Stillen G3's and Stillen exhaust, so would a tune be beneficial? I've had these on the car for about 10k miles...and I'm just not too familiar with the whole tuning thing. Any suggestions on a certain tune if I should get one?

[spearfish25]

A tune can get you some more HP (~10) but it's not necessary. Uprev is strongly supported here.

You should also reset your ECU after installation of these mods.

That's not necessary. An ECU reset isn't required after bolt-on intakes & exhausts are installed. Yes, a tune will give a better A/F ratio and give slightly better HP numbers (depending upon the maps used).

I would recommend at least getting a dyno run performed where they monitor the A/F ratio to see what the car is running. Sometimes, G3 intakes lean the car out beyond the safe limit where I could tell you that it isn't a problem: my car was detonating slightly before my tune after installing the G3 intake even after resetting the ECU. However, conversely many run the G3 without a tune and have had no issues.
