Just seeing if anyone here has tuned a high K ba xr6t in past. Mine has 357 000 on it (just engine everything else been replace in past lol) Now I'm not looking for heaps power. Only extra 2 or so psi and the tuner I spoke to said that's all he will go for anyway. Could plugs sensors fuel pump injectors actuator etc etc has all ben replaced so it has had a bit of money spent on all that. I'm aware sh*t can break but that can happen on any tune. And seeing I only go slightly higher I'm thinking I should be ok for now.. I know engine used to overboost to 10 psi for about a year straight before I discovered why lol Link to comment Share on other sites More sharing options...

It used to spoke to mainly 9psi but when it hit 10 it went into overboost mode so dropped cylinders etc. Seeing I'm not looking for heaps power just a slight increase if say I'll be ok. As far as I'm aware it's factory valve springs but I was told it had 18psi put through it buy previous owner before my mate owned it. So it may or may not have had valve springs done in past. Either way couple more psi would be good Link to comment Share on other sites More sharing options...
