when my car spools up to boost, once it hits full boost it starts to lag/sputter.
changed spark plugs and looked at the hoses for leaks. can't seem to find anything wrong? NEED HELP

 

When was the last time you got a tune and what mods have you put on it since you got it?

- Mods?
- Tune? and by whom, if any?
- Previous owner knowledge?
- Miles?

 

Talk to Aaron or Lucas @ English Racing. They have a PhD in the science of Boostology.

 

I haven't done any mods yet. Still stock. And it prob hasn't been tuned since before I bought it!

where in puyallup are you? im off south hill text me tomorrow ill take a look at it for you! ill inbox oyu my number

 

Check to see if your vacuum lines popped off... Or if you maf is connected completely... There are a thousand things that can cause this

 

im new to this world. still learning everything. so your speaking chinese lol

 

I speak Chinese (Mandarin/Cantonese dialect) and Japanese. Its simple really. Its simple really.

It means: MOAR MODS.

There, problem solved.

 

cool bro! just looking for someone with some knowledge on my situation.

 

And god cameth down from heaven and said:

"Google shall be your new friendth"

If you dont know a term or part... Google... Evo______ with said term or part in the blank.

 

It's most likely your spark plugs. Pull them and make sure they are gapped to .02, and are the correct heat range (should have a 7 in the part#).

Also, this isn't the best section for ?s like this. Use the search function, otherwise people will give you ****.

 

What part number did you put in the car?

If they didnt come from the dealer the only correct answer is ILFR7H gapped to 0.020". It is pretty common for even the dealer to hand people the wrong plugs.

Next thing on the list is a boost leak or vacuum leak that is screwing with the fueling based on the air the MAF is "seeing".

Thirdly, EGR lines when reversed or blown off can cause all sorts of issues.

Lastly, bring it in and we can look at it.
