See here, the boost keeps building till MAP limit above the target +10psi. I tied to use Map 6 with 8PSI and it still shot up to about 18psi. I have tried a number combinations in the software no joy. I will be checking the pluming again this weekend.

recheck your waste-gate hose routing. or disconnect the waste-gate lines and run straight spring to see if the gate is functioning correctly.

Sloppy Mechanics in da house!

Lookin good yo...hope you get the bugs worked out soon.

Yeah, I will. I didn't get to it this weekend so maybe next weekend.

So I removed the 50MM Wastegate and placed the new smaller profile wastegate right below the downpipe. I will be doing some testing to see if it is still overboosting and report back.

Your gate should be much closer to the turbo.

Place the wastegate at the vband next to the turbo then make yourself a dump tube having the wastegate closer will help you control boost better also I would make sure you got the correct hz boost solenoid. Temporary test you can please one of the stock ones that the car has to control the stock turbos.

Impressive good work, looks fantastic.

Thanks, I placed it just below the turbo and the down pipe off of the manifold. This is open dump and sounds amazing. I will have to test the stock boost controller because the Mac solenoid seems to be not working properly.

Make sure you have the ports wired properly if not car will build unlimited boost. Be very careful!!! On the other forum if you search jb4 single turbo there is a schematic for solenoid connections for the Mac solenoid and a link to witch one to use.

I have this same setup but with a gtx3582. I cant get the mac to work right either.

I think i will try a manual boost controller at some point, i know it will not work well but i am running out of options.

Any luck figuring it out? I'm still stuck at the 12volts to both sides of both boost solenoid plugs.

I didn't get time the weekend to check, maybe tomorrow.

You have to make sure your running the correct firmware for the Mac solenoid. What piggy back are you using ?

[alex_beridze]

subscribed, I am waiting torque and whp chart by rpm

[Levanime]

yeah, very interesting whats the limit of this manifold(s)

I think we all are running the most updated software/firmware posted to n54 tech. I know I for a fact am running the latest. I creep n54tech daily.

[Chris@BoostConcepts]

What spring are you running in the gate?

I would check your vacuum lines and also see if your waste gate even opens. This is weird when you welded wastegage vband was the wastegage attached???

A easy test would be to remove all vacuum from wastegage and see if it opens up around the same psi as the spring that you have installed so if you have a let's say 15lb spring it should open near that.

I have a FFTEC top mount kit, the issue is not with the kit at all, ive been DDing it at gate pressure for 4 months now (15psi springs). not once had an issue with anything hardware related except the solenoid. I'm getting 12v to both sides of BOTH plugs. Terry on n54 did mention to try running a straight 12v wire and tap into the boost control wire on the JB harness and check operation that way. If it works i will leave it that way.

I disconnect the vacuum lines, and it's still over boosting. Though not as bad as it did with the vacuum lines. I have a 14psi spring in the waste gate.
