I just had an Invidia downpipe installed on my WRX. I already had an HKS dowpipe on there but I wanted a better one. I had the ECUTEK done too with the HKS downpipe on there. Anyways, once I had the Invidia downpipe installed today my car is running like shit. The whole car shakes when it idles and it almost stalls when it idles as well. When I accelerate it barely moves and the turbo doesnt kick in until around 6000rpm and even then it is really weak. I dont know what is going on. Maybe my maps are screwed up on my ECUTEK when they disconnected the O2 sensor and plugged it back in but its scaring the shit out of me. If anyone can help me please do so. I need some answers now before Monday when I take it to Mastro. PLEASE!!! thank you

 

Is the actuator arm for the wastegate hooked up? The c-clip popped off of mine and it did the same thing. Semmed like the car had absolutely NO power (0-60 in like 20 minutes no joke), turbo wouldn't kick in (I never got it up to 6krpm) and exhaust was much louder, all because the wastgate was stuck open.

 

+1 ! Check the actuator arm and if everything is ok then, unplug your battery and hit the brakes a couple of times to clear all electic current and then plug the battery back in. This should reset the ECU and base tune allowing the ECU to start the learning process over again

 

The car is at Mastro and they said that my camshaft timing is off and that my camshaft sensor is bad or something. I cant remember what they said but anyways I pick it up tomorrow so I'll let you guys know how she's running.

 

I have no idea must have been a coincidence but I got her back now and she's running even better than before. That Invidia downpipe is so much better than that piece of shit HKS one. I got new tires put on two so everything is ok.

 

I have an APS SR30 turbo just waiting to be bolted on too. I just bought an APS uppipe and and APS DR500 intercooler. I just need a set of pinks and a Walbro pump and I will be in business.
