Well then killinprixs please tell me how to fix this issue. Even though my engine and trans are laying on hte ground I need to know, when it gets put back in.

the wastegate is opening, like Adam said its a 4# wastegate, running over 10# is more than double the load of the spring.  there are ways to fix this, you can either get a 10# wastegate or add an external spring to keep it shut and put how ever many vacuum T's before the wastegate in the line that comes from the boost controller.  i have notice that stock T25 will only make 12-13 psi with the wastegate unplugged and thats only down low , up top forget it.

Ok Guys been troubleshooting this thing for a few days.. This Coolant Temp Gauge issue is really getting to me  :icon_twisted: :icon_twisted:.. I got a replacement Cluster thinking it could be inside the cluster causing things to not work.. NOPE that didnt solve any problems.. Now bare with me here i might get off track or not make sense but ill try my best to get it through typing it out.. In order to check for a bad coolant temp sensor you ground out the green wire thats for the coolant sensor in the engine compartment for the gauge to peg into 260 to know that your cluster is working.. well when i do that i put a ground on the green wire my jumper wire gets hot and the gauge does not move.. Now why would the wire be getting hot when grounded out? the green wire runs off of OHMS.. Well i unplugged the cluster and tested it again and the jumper got hot even with the cluster unplugged.. so i decided to test to see if im getting power through the green wire and i am when the key is on the wire has 12 volts and with the key off theres no power.. I also OHMED the green wire and it OHMED good.. The only thing i can think of is that the green wire goes to the computer and from the computer to the cluster.. and the computer is whats giving it the 12 volts when the key is on.. Am i missing a step for troubleshooting this out?? so the cluster tests out good and the sensor i have should be good.. I just dont know why i have 12 volts in this wire when the key is turned on..

Also In the Neutral safety switch plug i cant figure out the reverse lights.. With the key off i have one hot wire and with the key on there is 2 which one is the thick purple one and the other which stays hot with the key off.. So i dont know why theres a hot wire with the key off..  :icon_question:

the gauge sensor its completly different from the ECU temp sensor! You are doing the right sensor right?

Yea I'm doing the right one. Dark green single wire on the rear head. I figure is throw the ECM part in cuz I really don't know. I know the lim cts goes to the ECM. I can't firgure it out though. When grounded it gets hot because the wire has 12 volts and I'm causing a short. I would think there shouldn't be 12 Volts in the sender wire.

well been awhile since i have updated my thread.. I made a quick exhaust video but plan on doing another one with the camer further away so there is no distort.. This video i had the camera 15 feet away and zoomed it in.. LMK what you think..

Sounds pretty good for catless/mufflerless. Not surprising though as these cars seem to sound about the same no matter what you throw on them. Both of mine with two different setups sound kinda the same...
