So what would happen if I drove it with out my fronts in ?

It would set a few codes and default to running in "open loop"

BottleFEED · 03-16-2014, 09:45 PM

Would I hurt anything ? Not gonna run it but I just was wondering about it

ZO6 Bryan · 03-16-2014, 10:18 PM

No, it wouldn't hurt it.

I've seen guys do it, and others say don't do it. Just wanted to get to the bottom of it. Thanks for the input !

So basically once you're reaching the limits of the OEM MAF, you need to switch to SD? I can't see our blade MAF being that restrictive to make SD something that would make more HP from switching.

Sorry OP, I guess I wasn't 100% correct. There are special considerations and a good bit of tuning required to run SD reliably. The car does have the abilty to run SD within the OEM pcm too and will switch to SD if there's a MAF issue.

You tune boosted cars on speed density so the tune can adapt to different boost levels without a retune.

You CAN tune boosted cars on speed density but it's mostly to get away from the restrictive MAF's. You still need to monitor the O2 sensor when changing boost settings to make sure you're not running too lean or rich though. For the OP, I don't know how well it will work for his situation. Even though it will be temporary, i'd imagine the OEM VE tables for SD in the PCM are set to a stock vehicle with zero mods. He's changed the VE of his engine with LT's and proably a CAI. Those may be enough to make him run lean. I have no idea how much leaway is built into the VE tables but I know SD needs to be retuned for pretty much any changes you make to the engine.

Go ahead and run without them and let us know how it goes for you.

Ran it up the road sum an back. drives an runs fine seems a little rich but I am letting it sit until my extensions come.
