Default About to hit the dyno. Any suggestions??

Hey guys like the title says I'm about to get the car on the rollers. Everything is mechanically sound. Tuner wants a couple cans of gas and I'm gonna leave him a pail of VP M1 and some boost cooler in case he doesn't want to go full meth. New set of plugs.

Anything else y'all can suggest??

If he tunes it for better fuel it won't run optimally on your regular fuel choice. Have it tuned with whatever fuel you would use on a daily basis.

That's what I'm planning on doing and what he's also suggested

I went full OCD and made a list for mine lol.
Fresh pump in the tank, 5-gal pail of M1 which we barely made a dent in, tool chest, extra plugs, plug gapper, spark plug specific tools, laptop, cables.
I wanted to be as prepared as possible and because I had everything under the sun, nothing went wrong, my tuner confirmed lol.

That's kinda where I'm at too. I'm just waiting on a 5 gallon pail of M1 to show up. But I'm fairly certain I've crossed all my tees and dotted my eyes.

Did you spray straight meth or did you try a water meth mix??

I went straight to meth since I knew that's where I'd end up anyways.
I thought about water meth and different boost settings, but I'm just not wired that way, I want it all in all the time lol.
I've driven the car quite a few times since the dyno and the meth tank has barely dropped so it's not even using a ton of meth which is great.
If you've been driving the car for a while like me then I'm sure you'll have no issues, I'd just run meth, its cheap, the kit doesn't use much, and the safety net is huge.

You'll be fine, you'll probably run out of injector too like I did.
Just be ready, you've got more turbo and more cubes than me, so you'll definitely make big power.
700-750whp was fun and was like "Oh this is nice and could get me into trouble tra la la la", 900whp wheel is a whole different animal, it's really too much for the street but damn is it fun lol.

Yea I'm hoping to see big power but we'll see what happens. I'd like to get some video when he does some max power runs. But I ended up pulling the 1200cc injectors and got a set of 1440cc in the car now so that should get me a little bit further

Don't get too hung up on a number either, I really wanted to see big numbers on the screen but my converter kept that from happening.
You may encounter the same issue, you'll definitely find out where the converters limits are.
Is the tuner using a chassis dyno or a hub dyno?

Yea I'm not about to get hung up on a number as there are other issues that could possibly arise. My converter is a year old it's a 10" billet single disc from FTI. Hmmm I'm not too sure what kind of dyno he's using as I've never been there but when I made the call I'll give him an ask. I'd assume it's probably a chassis dyno

I'm curious to see what kind of power it'll make. Your combo seems pretty stout. I don't think 900-1000 is out of the question.

Thanks yes I'm thinking the same too! But it's starting to look like a next week thing as the pail of M1 is taking forever to get in

I'm hoping he'll hit 1,000whp, that was what I wanted just for d!@k measuring lol.
There are only two questions really, will those 1440cc injectors and the meth provide enough fuel and will the converter stay coupled long enough to get the reading.
My Circle D converter started tapping out pretty early on, but we kept going anyway, the tuner just said the dyno reading would be way skewed.
I'm betting the converter is gonna say "No Bueno" before then but hopefully I'm wrong.

What did it look like on the graph when your converter started to tap out??

It would climb rapidly with boost then plateau and drop off towards the end of the pull, you can see it in the graph on the video I posted how it ramped up and leveled off quickly.
The tuner said to pay no attention to the number, the dyno loads the converter completely differently from how it will act on the street/strip.
I wouldn't even worry about it, if you're spraying meth and getting close to 100% IDC, then you've gotta be knocking on 1,000whp.
My 1000cc injectors supposedly support 1,260hp on pump gas plus twin M15 nozzles fire hosing meth is ample fueling to support the 900whp the tuner said its making.
He felt it was over 900whp, but I don't like to over embellish so I asked if I could say 900whp confidently and said absolutely so that's what I did, your tuner will probably do the same.
No matter what happens, you're gonna make some serious power my friend, no doubt.
On a side note, does your 4L80E retain full automatic function with the ability to down shift and what not?

I run a Dominator ECU so I can go full manual or auto at the flip of a switch. I'm running an M14 and M16 nozzle in my meth system. I'm not gonna be stuck on a certain number but I'd be over the moon if I were to see 1000+ rwhp.

Very cool, I wonder if the Haltech I'm looking at could support that.
If you end up over 20lbs. which I don't see why you wouldn't, you might not see the number but it'll be making it.
Don't get me wrong, I certainly hope you do, I just wasn't willing to chase mine and stopped with low timing and a fat AFR for a hopefully longer life lol.
You might want to select a dyno friendly tire if possible if its a chassis dyno, I had always been warned about using a bias ply slick on the dyno and been told a drag radial was best.
