Ok, so installed the greddy turbo with the e-manage ult, aem wide-band, and tru-boost.

For some reason boost will build up all the way to around 8-9 but it will not hold.
(doing a boost leak test

Also doing some tuning on the highway...and after the first pull timing drops out completely and the e-manage will not read any timing at all?.

Other then those problems at WOT the car runs smooth.

Has anyone encountered this problem? LMK please. and Thanks.

i believe there were some people experiencing problems with the EMU due to incorrect spark plugs. other than that recheck all your electrical connections

The wires are all good... because the EMU has a plug and play harness and the wideband and tru-boost I wired those myself.

The spark plugs i'm using are Ridium IX BKREIX same spark plugs that the first owner of the greddy used and had no problems with it. (FYI before I got the kit the first owner only put 1000 miles or less on the kit.)

what does the boost drop to at wot?

sounds like a boost leak....

g352s2k

I have it set at 10psi and it falls to around 7-8 psi

check for a boost leak, make sure the wastegate and blow off valve are connected correctly.

What i'm really worried about is the timing droping out... If I run the car hard and there's no timing and the engines gonna go bye bye. Also its an internal wastegate.

maybe its the way your Boost controller is configured, I say take that off and see what happens when you go WOT on just the W/G spring

I will try that after I check the boost leak problem.
