Did you try different meth/water ratios or just stayed with boost juice?

Anyone else fitted the pure st1 yet?

Already running meth so it seems next logical step.

Would be good to get some other opinions

Might be an odd comparison but how much of a difference would there be between a completely stock car running JB+ (or JB4 Map 1) vs same car with Pure Stage 1?

Does it make much difference on the top end?

Could be a good set up on pump that looks completely stock once you unplug the JB+.

Stronger mixtures are generally better for higher end power goals.

I am currently running jb4/meth kit (vp m1) and pulled the trigger on a pure stage 1.
My core is already sent in and received by pure, awaiting on shipment. Hoping for some good results.

Top end is noticeably better. Needs more fuel. Switching from meth to E98 was a big improvement. Turn time was very fast 2-3 days I believe is their expected turn time

shipping is the biggest thing it could take 2 weeks if you ship it ground. I live in indiana so no where near them.

Installed the pure today. Did a few pulls and it feels good so far (FUA10-50add)
One or two slight closures, I didn't even feel them. I will lower the add to 40 and try FUA0, as suggested by a fellow beemer broski.

So far I can tell ya it sounds different while spooling and it might have ~200rpm lag compared to stock. It definitely pulls harder over the stock turbo
I'm running pure, meth, AP intake, er ******** and muffler delete (figured I'd share)

Boost on Broski's......

Throttle closures/movement is normal, if you don't feel them they aren't an issue.

It's only when they are more than like 50% closed for more than a few seconds which cause hesitation and issues.

Or are you saying there is hesitation

From the 12 miles or so I drove after the install I had only a few closures, none of which I actually felt.

Pure 1 is a no brainer mod is you're running meth already

I still like to run 40 add. With x98 I can hit 50 add with no closures but the car doesn't feel as fast. At 40 add I'm right around 20.5psi at 50 21.5.

question....if fueling is still an issue, wouldn't it make sense to go with bigger nozzles? and is there a way to actually control pressure or flow on the meth kit to make it inject more?
