WOT Issues

[Joe Smith]

2013 PP With Livernios 93 Tune. 3Bar map. CAI. SparkPlugs.

The car runs absolutely beautiful regular driving. Even aggressive driving, perfect. WOT is an issue. Almost like when in full boost its rocking back and fourth at around 4700-5500 RPMs. Sometimes after a few RPM Cycle's it Straightens out. Bad Injector? Weak FP? I usually run Shell 93.

How long you have the tune? What version?

Its a recent update. I just went from stock, to 3 bar last week so the tune was updated. I had issues on 2bar as well

Did you have a 2 bar tune or stock tune. Just looking at tune vs oem programming vs something else causing the issue.

It was tuned on 93 with the 2 bar. I ran 7 months no issues. I don't think its the tune

Stored error codes?

Stored error codes?

No CEL ever came up. I don't think it stored any when I had the tuner plugged in.

Can you put your car back to stock?

yes, it still does it, but not as bad

Do you have access to sct or hptuners datalogging? I'd be half tempted to say fuel pressure is dipping but it's not in my practice to just throw parts on hunches. Also plugs that are warn and the gap has increased will cause stutters in the higher powerband

I agree with this as well.

+1 start with the easy things to check. Plugs etc.

What part of Ohio are you in? If you are near any of us that have an SCT device, might be able to help by hooking it up and watching a few things live like fuel pressure.

 

[FiveLeeter918]

agreed, sounds like either fuel pressure, or possibly knock. are you flashing a CEL or anything during the issue?

No flashing cel, i'm in the Columbus ohio area

 

[FiveLeeter918]

definitely need to find someone with SCT or HPTuners so you can log.

I'm on southeast corner of Columbus if you want to hook up and get a log to try to figure out what is going on.

or you could get the stock tune loaded and have a professional tech with a good diagnostic computer look through all the systems and see if it can pinpoint running and stored errors. always an option

I had this issue on my 2013 PP. No tune, but when I tried to gun it, the car would start jerking and rocking back and forth. Took it into the shop and they replaced spark plugs + coil boots. Issue went away after that. Might be worth checking out but like others have said, get a technician with logging capabilities to take a look.

Stragely enough I added some octane booster and fuel injector cleaner and it ran perfectly yesterday.. just a little smoke at WOT
