Initial tests:
Go-N Def, Dark Tech and I had our ECM updated to the latest Westers tune on Saturday and was seeing 23lbs of boost in every gear. It hit 23lbs really fast. We all previously had the Wastegate mod and tune. The new tune w/wastegate mod caused everyone's DIC boost guage to stop indicating boost after 3 seconds of WOT. Additional WOT tests indicated nothing on the DIC, yet you could hear the boost and feel the power. Go-N Def's external boost guage was still indicating 23lbs while the DIC reported 0. Once the car had been turned off and restarted, the boost indicated OK. So we had to come up with a fix.
The fix:
After several discussions and recalling the conversations about another tune that shouldn't be done with the wastegate, we decided to back off the hardware on the wastegate mod. I now have 3 threads visible on the right side of the rod. The Now the boost reads at 22 at WOT and the there isn't any issues with the DIC.
First impressions:
Holy crap, it is like getting a new car again, wait, it's even better. I have to be more gentle with the gas as to not spin the tires. The traction control light flashes more now "Low Traction"
This is the mod to have
I need to get to a dyno.
You may have seen LilGoats new Dyno Sheet post
Latest dyno run. He has the Westers tune and is seeing 22.1 lbs boost on the Dyno.
If you send in your ECM to Westers, this post is a must read
In the fuse box above the batter, pull fuses 42 and 43, re-insert the fuses after you re-install your ECM

I just got an email from Westers. If you are shipping your ECM, use the US post office Priority mail or Priority Global express, the Global express gets it there in 2 or 3 days, DO NOT ship on a Thursday or Friday and Wednesday is ify. If it hits customs on Friday it can get very delayed. Insure the package for $20 no more unless you want to pay the extra taxes, he has to pay taxes on the declared value. YOU WILL GET TO PAY THE EXTRA TAX! He usually does the tune the same day he receives the ECM and ships them back Next Day Air for free. I have shipped an ECM up early Monday morning and gotten it back Friday, it doesn't always work this well but it can.
I think I just made sure I had the VIN and sent it in, pick a number it is mostly so he can match up the form with the ECM in case they get separated. I just shipped it and sent an email. It is more expensive to use the Priority Global express which is Fed Ex through the USPS but it's worth it, gets through customs much faster. He will ship it back to you fast, it's getting it there that is a pain. Make sure $20 on the insurance and you must insure it! If you don't they open the box to determine a value and you are screwed for days in customs.
On his website it says to label it temporary unit for repair. is this necessary? In your earlier post you said not to ship on friday
Warranty return on the customs doc is important, as long as it has the $20 value should be OK. If it doesn't say return they get taxed as if it was a new item they are buying. It just cost them more to get it in, they will share the cost with you if they have to pay extra.
Here are instructions from Westers after you get your ECM back or with a new ECM, you may not have to do if you send in your ECM, but for sure with a new one, just in case here they are.
The 'passkey' relearn will have to be done...which has to be done first before the vehicle will even start up.
1. Attempt to start vehicle.
2. Relax key to the 'run' position
3. Anti-theft light will 'flash' or remain on solid for 10 minutes and then go off.
4. Shut key off after the light has gone out.
Repeat steps 1-4 again another 2 times.
These procedures have taken 30 minutes (minimum).
5. Start your vehicle.
I removed the text for the case relearn as the GXP's have a different ECM that the NAs and case relearn isn't required
