hey guys i installed a turbo back exhaust on my 2008 evo x along with a boost gauge. i noticed when i open it up my boost spikes to about 25-26 psi then drops back down to 14 or so is this normal? idk where to go from here .. lmk if you have any suggestion thx in advance ...

tune

is it because i added the mods? also will it be safe for a bit while i get the rest of the bolt ons on before a tune??

 

[chetrickerman]

do you have an Air/Fuel ratio gauge?

 

[REVOxGSR]

not yet ....

 

[chetrickerman]

you need one. Dont go into boost until you get one just to make sure that its not running lean in boost

 

[REVOxGSR]

would just the turbo back make it run lean?

 

[chetrickerman]

it can. Im not going to say it will because everyone's car is a little different

 

[REVOxGSR]

hmmm so going out to run is a no no tonight lol

 

[REVOxGSR]

lets say the car is not running lean yet still spikes the boost is this a problem or just a matter of tunning?

it should be

These cars should be retuned as soon as you change from stock. Otherwise you will have issues with boost, fueling, knock, etc...

problem is i have other stuff on the way i wanted to put everything on before i go get a tune dont want to pay for multiple tunes....

if you're just putting around town and not matting the throttle at every chance, you should be able to minimize the boost spikes and still use the car for transportation until the rest of your parts come in and you can get it tuned.

Guessing your rolling with test pipe?

if so your going to need a tune asap.

 

[REVOxGSR]

yes i do have the test pipe ... does that make a difference.... also everyone is saying i can still put the car around how about drive it for a while as long as i stay out of boost? had a snowboarding trip coming up and was planning on driving the x....

I'd get all the parts...load them up in the car with all the tools i needed...drive to the tuner....put said parts on in parking lot...get tune! That way you wouldn't have to pay the labor or worry about your engine going boom on the way there. I live a few hours away from my tuner and this is how I would do it.

? my tuner is in town my snowboarding trip is out of town .... if i get a air to fuel gauge and am not running lean then it should be good to drive right?

Why are you screwing with it. The $200 or so you save on a retune is peanuts compared to a rod through the block.

 

[REVOxGSR]

$350 a tune and this is why i am asking if its really that much of a risk then ill just leave it parked for the time being... but the dangerous part is running lean right so if its not then its fine ...correct?
