Boost creep!! Help

[Yosteak]

I am running TSP stage 1 and I am using Map 2 all the time when I get on my throttle the it shows 27psi and I am getting pretty nervous about my motor blowing up. I have read on the forum that it can be my intake. When I get on the throttle I get no CEL or I have not gone into limp mode at all wondering if anyone have any boost creep issues and how can I resolve this

Mod list
K tuner V2
Tsp Stage 1
Ma performance intake
Ark performance Exhaust
Mishimoto intercooler
Stock downpipe/ stock front pipe

I’m not much help when it comes to tuning, but that much boost when other parameters aren’t set for it sounds like a one way ticket to pound town real quick.

Baby that shit and find a shop that can diagnose the issue with the wastegate or why you might be getting creep.

27 psi on a stock downpipe? Doubtful. I'd guess the MAP sensor is reading incorrectly, and would hook up a mechanical vacuum/boost gauge to it to confirm.

First thing I would do is flash to a KTuner basemap and see if the issue persists. If it still reads super high you can look at something mechanical or as @WhiskeyTango said maybe a faulty sensor. If it goes away, maybe a tune issue and contact TSP.

Thank you for the advice everyone

I just have a hard time believing that the baby stock turbo is even capable of 27 psi with the restriction of the stock dp.

But your advice is the best way to go. Flash back to a basemap or stock and see if the problem persists.

Yea I was thinking that too but I don't know how accurate the dashboard boost gauge is

its accurate "enough". But I'd monitor boost values with a mechanical gauge, and also keep an eye on what KTuner tells you as well.

The intercooler/intake are the problem. That tune file wasnt really designed for bolt on cars (albeit people frequently use it with bolt ons- the degree of issues or not is subject to differences in each individual setup). If you had a hardware issue that was the "cars" fault then it would be coding and lighting up the dash.

All the boost targets etc do not know when you start changing parts that affect the volumetric efficiency of the system.

Bluntly, you need a custom tune.

Intercooler and intake? I'm kinda skeptical on that...

TSP 1 should handle those bolt ons without issues.

It literally says on the TSP product page that quality aftermarket intakes and downpipes are supported. No reason the FMIC would cause an issue either.

Just to note, if I recall correctly, according to Derek Robinson, "The MAP intake has the most inconsistent MAF scale requirements of all.".

Could be a small step into figuring out the issue.

@hobby-man If Derek says MAP intake isn't "quality", I'm gunna believe him on that.

 

[PowerPerLiter]

"Will work" and "designed to be used with" are two different things.

Derek has said it before that it was developed on a factory vehicle.

Can it be used with quality bolt ons? Of course.

Can certain combinations of bolt ons create issues? Obviously.

Im just telling you there isnt anything likely wrong with the car or the tune file.

Hes eliminated a rather large restriction post turbo combined with an uncalibrated intake.....all bets are off at that point.

Again, op needs a custom tune.

Absolutely. Especially if the intake isn't an Injen.

For the record, generally speaking a TSP tune does just fine with the mods the OP has. I don't know much about the MAPerformance intake though and Derek is skeptical. But that inconsistent MAF wouldn't affect boost numbers as much as it would fuel trims.

Quick question to the OP. Are you seeing 27 psi for an extended amount of time or just a split second blip?

Please post up a datalog.
