Fast Intentions exhaust is here!

xXxCarBoyxXx · 04-05-2012, 12:34 PM

I'm sure this has been answered somewhere but I've been looking around and there are a lot of mixed answers flying around.
I'm looking to get the Fast Intentions CBE with the 12 inch resonators in the near future and I'll be installing Post-MAF tubes and k&n drop ins. I wont be changing the headers and I probably won't be getting HFC's any time soon.
With these upgrades will I need to get a tune? Will the car run fine and not too lean with the stock tune?
Thanks

I would if you are replacing the cats with TPs or HFCs to go along with the exhaust.

you will be fine with no tune until you add HFCs..

So you're saying that filters and Post-MAF tubes are enough to lean out the air fuel ratio with full exhaust mods? I thought is was aftermarket intakes that did this because they have larger MAF sections/different MAF locations, or will anything that frees up the intake a little be an issue?

Just wondering if I can just save up for long tubes or if I need to add the cost of a tune on there too.

this is strictly my opinion. There are plenty of guys running all those mods with no tune however I imagine their AFRs are pretty terrible. If it were my car, no matter what intake (besides drop ins) and a full exhaust, I would tune it.. Its better to be safe than sorry

I just contacted Nissan regarding this, having just upgraded my HFC/CBE and have a K&N Typhoon Intake. I told the Service Manager whom I trust that I just upgraded my exhaust, but its nothing more than what a NISMO would ordinarily be. He stated emphatically that there is no need for a Tune. Again the pharse is " NO NEED " for a tune. You won't burn a valve or damage your engine simply because of a simple Intake and exhaust upgrade. Unless you go Turbo, Supercharger, Nitrous or anything beyond of what a VQ37VHR is asked to do by the factory, the car should be fine. If you track the car and push it to it's limits, then it's a whole different ball game, and you may want to tune because you are looking at optimal power, not just a fun ride.... You can still tune it if you want regardless, but herein lies the risk. You tune it, something happens, Nissan can claim you tampered with the programming on the computer and hence your warranty is void.

Now it's up to each individual to make up his/her mind what they want to do. Upgrade hell? Here it is... Decision making time...

The worst part about having a warranty is the thread of losing it.

Per my discussion with Tony when I ordered my LTH's and CBE, you DO NOT "need" a tune. He even went as far as saying from their testing, it was only the Stillen Gen III's that when added to full exhaust mods would need a tune. If you're that concerned about it give Tony a call and discuss it with him. He was more than helpful back when I ordered mine.
