Guys,

I have searched around a bit, found some informative stuff, but I still would like to run this past most of you with more experience on this....

#1. My brother is an Infiniti mechanic, he said that I "shouldn't need" a tune after I install my Crawfordz cats this weekend.

#2. My combo is simple, something the ECU can work around, Stillen cat-back, drop in K&N, Z-Tube, 5/16" spacer, and that's it. Not really aggressive mods in my opinion. I read a thread about a lean condition after installing HFC's, but maybe that was an isolated incident (looks that way to me)

#3. I know I SHOULD get a tune to get the most out of my mods, and have contacted MRC Motorsports regarding this, but I would like to get it done in the Spring as opposed to right now. Will I be "safe" driving the hell out the car from now until then, or should I get the tune to avoid any kind of damage?


Thanks.

Don

 

My car has never been tuned. Runs fine.

 

i have not had my car tuned, although i certainly would like to. makes me wonder if i could squeeze a few more horses out of my mods if i had it done.

 

Naa.. you don't need a tune and waiting until Spring shouldn't harm you. But it should be good for a few horsies when you do.

 

Do a dyno pull to check your a/f ratio. Revup ecu will compensate more for it. I have cams and my car isnt lean.

 

+1 on the dyno pull to check your A/F ratio. You should be fine though. Nothing to worry about with those mods.

 

After I got cams I needed a tune.

 

+1 on revup ecu. OP, you didn't say what you have, but the revup ecu definitely learns breathing mods well. If yours is revup, take it easy the first couple hundred miles after install if you are concerned about it, but after some time to adjust you will be fine.
