first post by me, but this (long-long) thread has helped me make up my mind so it was worth the sign up.
I have a manual MN Triton set up to go pretty much anywhere I point it. It has a canopy, moderate lift, a snorkel and breathers, catch can, fully sound proofed, winch, 2 ½ inch exhaust and bars front & rear. It is heavy and in no way is it quick, but it is reliable and rock steady and I like it like that. The only issues I have had is with the OEM Boost controller causing over boost, so I bought a new OEM solenoid valve, and it was perfect for 8 months but then it started over boosting again.
So, this time I bought a Tillix valve & needle valve and had it dyno tuned last week by Lindsay Burrows the owner/inventor of the Tillix valve.
But ever since then it runs hotter by the Temp gauge, it has risen to 3/4 a couple of times in the last week & it has never done that before, it always sat on ½ and never ever got any hotter. And by the boost gauge it can now boost to over 25psi, if I stand on it I can get it to just over 30 psi, and I have noticed the exhaust manifold creaking and banging (heat expansion I would think) but it is doing it while I am driving it and I can hear it in the cab & it has never done that before either. I think that the heat under the bonnet is now affecting the clutch slave cylinder as well because the clutch feels weird after it warms up as well.
But the final straw was today when I got an engine light (but not limp mode) while I was in 3rd and accelerating hard. When I cleared the code the OBD11 car scanner said something about boost pressure.
This is the thing about Tuners, in my experience a lot of them just try to turn your vehicle into a race car & push it to its limit, but this is a dirty old slow revving diesel ute & if I wanted a race car I would have bought one. All I wanted was for it to max out at about 18 psi and boost no higher. I do not see the point in trying to break the land, sea speed record in a heavy 4x4 Triton Ute.
Yes it drives better with the Tillix installed especially in low rpms, but something else is happening to my ute that I do not like, it is the first time I have ever had this feeling that something is going to break, & I don’t like it. I no longer trust the old beast with this Tillix valve installed & I am not going to risk it any longer. I am removing it tomorrow and getting another Denso Boost controller. But this time I am going to mount this one on a rubber vibration & heat retarding damper & see if that makes it last a bit longer.
