My intention is to run this at a safe power and PSI until I replace the OEM rods by forged ones next year.
Does someone has a similar setup that has been proven to be safe for a while?
I would like to see your boost target table (dyno if possible).
Other things that I should be aware of?
Thanks to all
From my experience you should set your limits first. I'm assuming you've got your fuel and spark tables tuned to 200kPa? If not then stop here until you have.
First set your over boost protection up, then you know you can get the table boost wrong and it'll be ok.
I've set mine at 180 kPa fuel cut
Then do a WOT run log with the table at 100 throughout to find out what your wastgate only control is taking you to.
Then decide where you'd like to be PSI wise. Remember that 14psi will be around 200 kPa
If you decide 10psi is your target start by reducing you boost map in small amounts across the board, probably 90 to start with to see any effect.
Then its the fun part, WOT runs in 2nd and 3rd to get the info you need, then if you want feedback post up the logs.
I aimed for 9psi in 2nd gear at 3800rpm holding steady then to the redline. I found that this table then ran close to 11psi in higher gears but just low enough not to over boost. It's a case of adjust, log and analyse.
