One thing I'd say to check jess is the flange on the wastegate, some companies use a 'cheaper' so to speak flange and these fail. Nothing else to worry about in terms of the turbo hanging off it
With camber bolts and standard struts with lowering springs I was able to get -1.5 with no issues. With the meister's in that's where I had problems, needed shorter arms then. Funky power do them for around £70-80.
If the car goes into limp mode for example
the intake cam sets itself at 0 and just runs in that so it’s important that this part of the fuel and ignition tables are fully and correctly setup.
Just my 2p, this is often ignored..apparently.
