So I finally got to get to the Dyno here now waiting to get set up, I'm making 6 pulls and seeing if there will be any difference with the open BBS I take Vs it with the AFE intake box cover. All pulls will be with the hood closed also.

Mods are
Wedgecustom tune 20PSI
VSFR 5 inch intercooler
Pheniox Racing CP
BMS intake.

No DP's
And stock catback( flapper mod)
6 sps auto XI sedan
I will also be logging and videoing the pulls

[ANMVQ]

Three pulls done middle pull was 407 wtrq and 289 WHP, the Dyno I use is also the lower reading " truest IMO" around just took off the AFE cover and letting it cool a bit

Boost was 21.7 AF's look solid at 11.8

[ANMVQ]

Wow ok leaving the AFE cover on, two pulls I decided not to make the 3rd pull WHP was down to 277 and wtrq was down to 376 :/ open filter is no good.

Boost was down to 20.5 not a lot but still different than with the cover on

I'll take the torque numbers all day long, but those HP numbers...huh. Curious to see the runs when you're able to post them.

AWD dyno or did you disable xDrive via the fuses?

[ANMVQ]

AWD Dyno, not sure what the AIT's should look like but they were in the 140's.

Again this dyno is "known" to read 15% lower than any other one near me. I've been using this dyno for years. My bolted G made 324 WHP and 272 WTRQ here last year

Dyno compare without the cover was the lower of the 2 runs. A lot lower I was very surprised. I could actually see the difference in the runs, one the ones with the cover on the azz would squat, with is just seem to stay the same height ?

Dyno vid,butt sinks

What fuel were you running?

[Johnny Boost]

What was your baseline? Curious because 289whp is basically stock.

[FireBlaze]

Thanks for sharing your experience. Happy to know the cover won't hurt performance of the BMS intake. I will definitely be leaving the aFe cover on until further notice.

This is exactly what I was thinking.

[BoosTonian]

I hope it's not running sub 300whp at 20psi...lol

Shell 93 run it all time from the same station always

I have no baseline but I can tell you a stock car on that dynos not putting down 289.

No surprise from the logs. Crap tune. Mentioned this weeks ago and posted a virtual dyno of his log. Was attacked by an idiot...

[JETmn]

Definitely some work to be done on that tune. Timing corrections everywhere and isn't holding boost well.

It's the octane not the tuning. You are at the limits of 93 octane at 200 load. You pretty much have to run 0 timing advance in 3rd gear and even then you'll still get retarded timing due to corrections. I've been going through the same thing with Justin.

A lower load target tune with more timing (without corrections) would probably put down better numbers. Some people have been posting "94 octane" logs which I'm guessing means they are mixing in a few gallons of e85. Chances are those logs are really done with e30 for closer to 96 octane. I really didn't want to have to move to e85 but it's the only reasonable way to bump octane enough to get any more agressive.

Edit: I went back and saw where this is exactly what you pointed out to him a while back. You can run all the boost you want but if peak cylinder pressure is occuring after the piston has already traveled half way back down the cylinder you're just not going to create power.

I guess that's what happens though when you're etuning just to make the logs look good instead of tuning on a dyno too to see how far off mbt you are. The log above is clearly knock limited.

So are these all things Ken can fix without me traveling back and forth to the Dyno. I sent him this log today.

Yes he should be able to get it sorted out.

[ANMVQ]

Ok cool, I hope so,

Can someone explain what the "load" actually does? I noticed that when we turned this up I steered having sputtering issues( HPFP) and a huge drop in fuel pressure, so I replaced my HPFP. I still see a drop tho? Thank you

[ANMVQ]

Does this look any better? I went back to an earlier tune we had?
