Hello, sorry if I'm posting this in the wrong place.

I have a 06 Evo 9 MR that has recently just turn 22k Miles. Soon as the car turned 5k miles I went crazy and bough just about every bolt on available to the car, some of this mod's are (Perrin 3" Turbo back cat, Injen Turbo/Intercooler Piping and Intake Kit, Turbosmart BoV, Greddy Profec-B II, ARC Fmi, Apexi AFC neo, Rally Art spark plug with Iridium 2 stage cold plugs, no ECU Flash) car is Boosting 22 psi. All this was installed professionally except for the plugs witch to this date I get question as of why 2 stage colder! I don’t now either, though it would be better..."Kick me"

My Question is: While driving last week I notice that the car is not responding like before. If I Flore it, it cuts back or feels like shutting down, I can drive it at normal speed but just can't Flore it or give it any kind of boost, did my Turbo just died? Fuel pump? My Mechanic has gone on vacation for the Holydays, just would like to now if it would be safe to drive the car without giving it boost till He gets back next month....

Sorry if my English makes somewhat no sense, this is not my primary language and sorry if I sound like a Noob but, I I'm
Thank you for any Idea's/advice’

MTE.

 

Definitely the wrong forum, brother. This is the forum for the EVO X. But since you're here, I'd say the first thing to do is put in a regular set of plugs to see if yours are crapping out or just not right for the application.

 

 

well since you dont have a tune and you're running all those bolt on's with 22psi, maybe you're getting some knock when you floor it and the ecu is reverting back to the low octane map. Turn down the boost a little and then see how it feels.
but i'm also a newb and that's my 02 cents.

 

As someone mentioned before, this is the wrong forum to be asking these questions, but I feel quite sure of what is causing your problem so I'll help you out. As someone mentioned earlier, your plugs. The reason, to expand, is that you don't need to be running two step colder plugs. Just to give you an idea, for every 75-100 hp increase over stock, one step colder plug is needed. You see, your running plugs that are meant to have the kind of heat generated from 200 hp more than what you're making. You're running WAY too rich as a result, and you're fouling out your plugs. This would be more noticeable under full throttle, as you're dumping a lot more fuel in the combustion chamber than during cruise conditions. For your current application, just put the stock plugs back in. And BTW, get your ecu reflashed, it's the only way to go. Ditch all the crap that you currently use; the greddy profec, and all that other garbage, run everything electronically via the ecu. You'll see improvements in overall driveability, as well as a lot more power. With your current mods, you'd be lucky to be making more than 30 hp over stock, with an ecu tune you should expect another 20+. Hope this helps, good luck.
