some cars (even the same model car) react differently to mods and venting to the atmosphere. some like it, most hate it if theyre MAF cars. either way its throwing your tune out the window durring shifts.

 

why is it throwing my tune out the window during shifts? ur saying a tuned car with vta bov is useless?

 

you need to have it tuned or go back to stock,you will run faster stock.

 

a MAF carwill never run right, especially mitsu's and their Karmen style MAF when venting to the atmosphere. i know it sounds cool but it will never run right if you do it...

Well really the 05 MAF is designed slightly differnet very little change but is differnet. But still yes you need a tune if you get a intake.

 

When you say tune, do you mean a mail in flash or a dyno tune, to get the intake to work.

 

Just pour some water in to your intake to clean it out. Everything will be fine then.

 

Ugh, by tune he means any tune. A mail-in flash is one type of tune. A dyno tune is nothing more than getting tuned on a dyno by any tuning device. It's not some magical thing a dyno does for you. A tune is a tune is a tune - without one, don't get an intake.

 

I've tried searching...but just coming back with thousands of "which is best", "is this right", and the classic flame-retaliations. I'll just piggy back w/quick question.

I'm reserved to get tuned in 2 weeks down in Tucson (Im in Phoenix) (1.5 hr away drive). I'm interested and plannin on getting the Injen intake (already have lower turbo-side IC pipe installed). I KNOW that once the intake is on it requires a tune/reflash/_____.

Some people might just have the shop they're getting tuned at install the intake and tune it right away. Others like me, would rather save that $____/hr and do it themselves. My question is: Is it safe/do-able to install the intake myself, and then the next day or so (once proper installation verified)drive down to Tucson to get the tune that'll compensate for the new intake (plus other mods)?

No sense in getting the intake done locally, reflashed immediately for it, then driving down to Tucson to get a custom tune. Thanks for the help!

 

I did the same thing and was fine. I didnt notice any differences in the driving characteristics from stock box to Helix intake pre-tune.

 

This is probably a dumb question, but is there any way to tell if my car is tuned? My Evo was bought used and it already had an AEM intake in it.

 

YES I couldn't agree more

 

i don't get it... why does my intake work fine? no idle problems... nothing... i even have a biggie intercooler no tune... works fine... why???

i seriously believe that most of the poor idling etc threads from intakes is from dumb asses plugging the wrong **** into the wrong nipples and then coming here and whining. don't expect to get power from an intake. i did my intake for different reasons. but seriously... i'm one year wtih no toon... and **** works fine...

 

I have an 03 with just a Buschur intake without MAF pipe, and my car runs perfectly fine. This is with stock exhaust. IIRC on a previous intake thread it was mentioned replacing the MAF pipe changes the airflow enough to effect it more than just putting on a cone filter to the existing pipe, requiring a tune.

I do have one question though for proponents of the stock airbox. Why when Buschur tested an 03 and changed only the stock airbox did he gain 7ft/lbs of torque with no tune?

If someone can convince me this was an anomoly, I will forever convert back to the stock airbox side...
