Problems with ATP SRI & ATP 3" Inlet...HELP!!

[thanotosq]

Okay, so i had some problems with the inlet at first (see thread in this section about 3" inlet and Injen intake problems), but it got figured out....by buying new s***!!

Now, the problem is that when taking a test drive i had a complete loss of power at about 5500 rpm...not to mention throwing wheel weights, but that's another story... So, i parked it, re-set the ECU, and took another test drive... Bad things man...

This time around i had bad stuttering issues between 2000 and 2700 rpm. I also, still had a complete loss of power at 5500 rpm. The car seems really linear between those numbers, but around the top or the bottom...bad things.

Thoughts? And no i dont have any guages or a dash hawk yet, but that was next thing on the agenda...(uhm)

Thanks....and i know and feel that i am an idiot for not having guages...

How's the car running a few days later? I just saw this post. Depending on situation the ECU needs time to relearn, so that could cause sputtering issues. If you're still having issues, it could be numerous possibilities. Are you running stock or aftermarket BOV, if so, what kind and are you running recirc or VTA or both?

I had this almost exact same problem just trying to use the ATP MAF adapter and an AEM dryflow.

Did you do something to eliminate the problem??????

Did you use different components???????]

Did it get better????

How about some more insight into the problem?????

Okay, sorry for the slow reply

First thing i did was talk tp Ken from PG...because he is the best... And he said that it maybe fuel cut due to the larger MAF housing. He also said that multiple people have had problems with this SRI...

Secondly, i called ATP to get a return number or something and we started talking. That guy, who also seemed knowledgable and nice, said that it is not fuel cut, but rather, boost cut due to the stock ECU cutting off the boost in higher RPM's when it "thinks" it over boosting. He also went on to mention that there were a lot of MS6 drivers that had the same problem and the following are the solutions that they gave them: 1) get an engine management solution or 2) get their Boost Cut Killer module and an A/F guage. I personally think that that info would have been nice up front, but appearntly it only happens with car using the 3" SRI & Inlet (not just one or the other).

I was planning on getting guages anyway, so i think that i am going to try the boost cut killer route. Mainly because the combo of the 3" SRI and 3" Inlet is freaking insane and i found someone selling the Boost Cut Killer module on here for $55 shipped.

Besides, i really didnt get those kinds of gains from just the Injen CAI and the stock inlet. So, i am just going to sell the Injen CAI to someone less adventurous (or stupid) and go this route for now.

Another observation was that the Injen CAI actually fit inside of the ATP housing... kind of funny...maybe that's why there is more freaking boost!!

I am, currently, running the stock BOV... But i think that the problem lies at the intake manifold (i think, remember...i'm a chemist, not a mechanic) where the ECU says "hey, what the f$#k is going on! that's too much boost!" and cuts off either the fuel (Ken's idea) or the boost (ATP guy's opinion)....

Although, right now i have no idea how (maybe the waste gate?) the ECU releaves boost pressure other than the BOV, which is controlled by a spring...(uhm)

You're better off waiting for a good engine mangement system since I've heard very bad stories about the fuel cut defenders. Some people have had luck with them, others end up blowing their motor from overboost.

 

[thanotosq]

overboosting you say...blown engines you say....(yupnope)


well, i hope that you mean feul cut defenders and not boost cut defenders because that's what i just bought....(encourage
