Ok I moved the nozzles so that they're in the not pipes now. But unfortunately I'm still getting 4.5 degrees of knock retard. I'm gonna shut the meth off and check for knock on a tune with not meth. I didn't have any before so I don't expect to see any now. But just wanna confirm it's only a meth tune issue. Now my rev 6 meth tune only had 1.5 degrees of knock retard. I can live with that but that tune leaves a lot of power still on the table. Here's a pic of my new setup. Both nozzles are installed after the wastegate mod.

I took the car out and datalogged a non meth tune from 1st gear through 4th. There was only 1 degree of knock retard. I then loaded the rev 6 meth tune and only got 1.5 degrees of knock retard again from 1st gear to 4th. My next step is to pull the plugs and check them. I do have one question regarding meth consumption. I filled the windshield washer fluid jug to the top with meth. When I got back from the datalog I refilled the jug and noticed it used at least 18 -20 oz. of meth. I only sprayed meth for about 12 seconds using (2) 175 ml nozzles. Does that sound excessive?

I have no experience with meth but that amount sounds excessive for only 12 seconds of use.

X2 & Glock is spot on!! IMO that's certainly an excessive amount for such a short period.
I only consumed roughly a quart of Methanol during my 3 runs @ the Track with my DPM Setup. Z

My thoughts exactly... I'm gonna check the system for leaks. What is the total amount of mls with your direct meth system?

My car GOBBLES meth .. if i am hard driving i can drain the 3/4 gallon tank in a day.  on topic, 1.5' knock is not really knock its the car sensing there will be knock if it goes any further and pulling back.

what was the spark value with the 1.5 kr ?

I would also check your CAC(intercooler)for inundation.  Z

Are you using a solenoid or check valve on your system prior to the nozzle?

@- ddlopes I want sure if this was referenced towards me!!!
I currently have a Alky-Solenoid which acts as a check valve on my current DPM Setup. Z

Here is my very own thread below.

I have a check valve right behind the nozzle... I go to the track and run all night on window washer tank of meth with plenty to spare.... 10 1/8 mile runs....

I'm running (2) solenoids because I was injecting after the throttle body. My primary solenoid is right next to my pump and the power solenoid is mounted next to the firewall. Here's a pic...

I'm gonna drain the meth tank and put some new meth in there. Just to eliminate that as a culprit. I bought meth from a different supplier than I usually do. But it was a sealed vp fuel metal jug. But gotta check everything. Hopefully I get to the bottom of it soon. This sucks...
Brad also has me datalogging all the DMR's for knock so we can see what cylinder is have knock retard...

Just found the date on the bottom of the metal can... 8-20-2016.
Not sure if that's too old or not.

Check out this datalog... I think the knock is gone!!! I had to get out of the throttle because a car pulled out in front me.

Bad meth, eh?  Well, if that was the problem the Rx is of course to use it up as quickly as possible   Good find.
