I currently have motordyne art pipes and catback, also have injen long tube intakes, my question is, do I need a tune like asap? Or I can drive like this with no problem for a while?

Thanks

 

You can drive it just fine no issues ..

 

You will be running lean because of all those mods but stock ecu will adjust the timing enough to compensate. Doing a tune will make everything run much smoother and will gain you some power by returning the timing back to normal and adjusting your air to fuel ratios. However you are not hurting anything if you never do a tune.

 

Okaaay good to know , thank you guys

 

Dude get a tune! I was a skeptic at first just like you. After I installed my Stillen cold air Gen 3 the tune really made that thing come alive.
Dyno numbers were proof enough let a lone seat of pants driving.

 

I really want a tune but I also don't.... I have a CPO and right now if something awful were to happen I could unbolt everything and take it to the dealership for fixing.

I have HFC's in the mail and was really hoping I could run them with Injen SRI w/z1 silicone tubes, and a Tanabe exhaust without a tune.

To be honest the only number I am worried about is AFR with these mods, the HP and TQ will be whatever, just want to make sure it's safe.

I guess I should just pay for dyno time after install but untuned to see what the AFR is and decide then.

I live in STL and the only good looking place I can find to do tuning/AWD dyno is ET Tuning in Washington MO.

Anybody have AFR numbers with Intake,HFC,Exhaust without a tune? I have searched a million times and cannot find anything specific to those mods and the AFR results.

 

Cai, hfc, uim, cbe, no tune. Off my torque app on idle few weeks ago.

 

Lol interesting, I forgot I have that app
