Also, you need to get the right turbo on there for that tune! Or at least have someone lean down the fueling since its not going to be flowing the right amount of air relative to MAP sensor readings at each spot on the fuel map (which is probably part of the reason you use so much fuel, and the car is not that fast).
Yup, just finished getting the TD04 installed. Boosts only to 15psi. Switch to base boost, and it shows base of 5psi.
With the T25, I was getting a full 19-20psi.
We had to separate the exhaust and compressor housings from the turbo in order to drill out one of the studs on the exhaust flange, and we separated the wastegate actuator to do that. So that may have messed up the base boost.
In any case, I need to get base to what it should be, then I should see full boost, and get my power back.
So you think all TD04 are created equal? You think a TD04 18t is not a TD04? Did you get that info from the person who wrote the tune? Will a TD04 13t work fine? Its a TD04, I can't see why it wouldn't with your logic
please think before you mock me.
(although now I see that he says 15t - but just saying TD04 does NOT denote what size)
Point that has been made many times. Jak will tell you this himself. When you need more base boost, I needed 7-8psi for my stage 3+, you should, in my opinion and others, not shorten the rod, but add a helper spring.
When you shorten the rod, you shorten the travel and then the waste-gate cannot open as far to dump boost if needed to save the motor.
The better option is to add a helper spring that will be adjustable, give you the base boost you want and keep the full travel of the actuator and waste-gate.
You can get the perfect spring from advance auto, its the brake pedal return springs, 4 in a clear pack for 5 bucks. Pick the one that is around 2mm wire diameter. Put the hooked end on the actuator bracket and then measure the straight part of the wire at the waste-gate pin. When you ben it so it will wrap around the waste-gate pin, you want the spring to have to stretch about 1/4" to connect to you're mounting point at the actuator bracket. This will give you rigth at 7-10psi base boost. Then you can shorten or lengthen the bend in the hook to adjust base boost.
The assumption that I failed to verify the proper turbo for my tune before spending money on a turbo, and investing the time/effort/energy to install said turbo, it's bothersome.
Why do I even bother... because obviously I'm doing it wrong, 100% of the time.
I'm sorry if I came off as mocking you JK, but I hope you can understand my frustration.
yeah, it drives, and pulls nice and hard... it just burns oil.
