Hey guys need some advice from those who chip their TT. Currently my father have the upsolute chip in his car. Recently the car have some spike issue. After coming back from the track event he told me that he see 1.3 to 1.4 boost spike. I know this isn't normal. When there is a spike, the PSM and ABS light will come on on the dash. Every time it came on, he will need to pull in the pit and turn off the car then restart the car again so it will go away. We took it to a local Porsche dealership and replace the faulty diverta valve to a factory steel one already. However, the problem is still there and we can't really push the car. The dealership said is the problem with the chip but I want to see what are some of your insight on this.

Thanks would be a lot of help.

 

Need more info here...don't think we have the whole story. The "spikes" and the PSM/ABS may be unrelated. I don't think spikes in the 1.3 are that big of a deal...when do they occur? What is sustained boost in 3rd or 4th WOT?.

Next get the codes read....I say again...GET THE CODES READ!...we can help better with diagnosis if we know the actual codes....could be leak, MAF, etc.
