Default So am I running too much boost?

After the dp install, I'm hitting about .12 mPA in third gear (don't know about fourth).

Do I need to crank the boost down a bit? Am I in any danger of damaging the engine?

what is that in psi?
After my dp install i was hitting 18psi and the car would freak out feel like I was hitting the brakes and the cel would come one. I hit that damn fuel cut like 4 times. As for damage my car is still running, but we will see, I finally got it retuned and it is fine now at 15psi. Oh btw make sure you carefully install the probe back into the dp, at cobb they told me some guy fried his cpu and unichip when he had it twisted funny and the wires touched. just a piece of advice.

That's about 18psi. You are going to hit fuel cut like WR-REX if you stomp on it. If you are running a unichip you need to get retuned. I think fuel cut is at 17psi, not positive though.

I was pretty careful with the 02 sensor - I untwisted it when I put it back on.

I think I need to at least crank down the TXS ABC a bit to run less boost, or take the unichip off and get it remapped or both.

Whats the rest of your mods? My RT Spec sr30 peaks at .125 MPa. The danger is not just boost, the the temp of the charge being produced, the efficiency of the turbo and intercooler.

Manual boost controllers are cranky this time of year due to the cold weather (dense air). I would turn it down a bit to be safe.

I went through this same activity after my uppipe and downpipe install. I did, however, remap to the TXS Stage 2. I still have to mess around with the TXS ABC once ina while to be safe. (i'm running at 1.1mpa's at WOT in 4th & 5th)
