New 370Z, time for intake/exhaust

bigpat728 · 01-16-2013, 02:11 AM

i'm in the same boat as you. i got my z about a month ago and i'm ready to up grade. i think i made my mind up with a fast intentions exhaust. but i think i'm going to go ahead and get a stillen g3 intake. but i heard that if we change out our intake we have to get the engine tuned. is that true?

Congrats on your new Z as well. Glad to hear that you have taken an interest in our products. Do not hesitate to give me a call if you have any questions or would like to place an order. As for a retune being necessary with th G III intakes, it is not. The combination of the intakes and either stock cats or high flow cats and a cat back exhaust will not require a retune. Now in the event you run the intakes with our long tube headers and cat back exhaust, I recommend a retune. We have found during extensive dyno testing the 370Z likes to run a little lean with the G III intakes, long tube headers and exhaust. The retune will do a nice job in making your Air/Fuel ratio optimal.

Thanks, Tony

As Tony said, its not necessary but a lot of us get it done for a few reasons. There will be people who argue that point as well saying you don't need the tune, you get almost as good of numbers with out a tune and such. The tune is not just about power. Its about balancing a car. Smoothing out the A/F ratio, bringing the mod's together to work with the car perfectly. They will work with them anyway but a tune like UpREV will definitely add nice touch. If you think about it, you spent $30k+ on this car, treat it like the nice car it is. 30 grand by no means is chump change in this economy.

and on the side note. if you go with test pipes you're going to want that tune so you don't have check engine lights all the time. The tune can shut off those sensors affected by the test pipes that will throw the codes and with the tune you wont have to worry about the way your car is running with out those sensors
