Inconsistent Throttle Reponse

[k31th]

either way, the tuner should be able to sort it out, so take it back to them to diagnose it.

That's what I'd be doing unless I was going to fix it myself.

Unfortunately old mate at Autotech didn't give me any proper time when I took it to him, just dismissed it as they couldn't recreate it on the day, didn't even bother to read the codes and I wasn't about to hand him more money for an issue he might've created.

 

The car idles super smooth, even when the issue is occurring. Never had this issue when it was stock.

 

Surprisingly enough when I drove home from work today the issue happened without any thrashing at all, it was easily 30+ degrees outside, and began once I started hitting red lights and sitting in traffic. Super annoying and was totally inconsistent.

 

Mods are:

-Plazmaman intercooler (piping retaining stock crossover)

-Walbro 340 

-Siemens Deka 60lb 630cc Injectors

-Xforce full exhaust set up

-Plazmaman stage 1 valve springs

Tuned at Autotech making 275rwkw @ 10psi from memory. The spark plugs and coil packs were replaced on dyno day and was assured they were genuine by old mate at Autotech.

 

I'm gonna go get the codes read once this holiday period is over, but my knowledge of OBD system is 0, but I'm assuming its the best step to finding out what the issue is.

Tuned by a very good tuna,

He uses SCT yes? U should be able to use your x4? To pull codes.

Any news?

Sorry on the late update, forgot about the follow up.

 

I pulled the codes using my SCT X4 but nothing showed up, apparently the car is running smoothly. When the weather chills out I'm going to have a geeze at the throttle body and the tps to make sure nothing is dirty or faulty. Issue is still super frustrating its almost impossible to predict and as a result hard to recreate for a mechanic.
