^what this guy said, no amount of tuning, elevation, gas etc is going to make your car down less than the guy with megan headers and lacking airbox

If I were you I'd check compression and do leakdown.

Something is not right.

Ya, def a mechanical/timing issue going on there...power just looks down everywhere. It's also nosing over around 7,500rpms, and it should pull to 8,200+rpms no problem w/those mods. GL getting her sorted! I've been chasing similar issues w/mine, and 99.9% sure it's still somehow VANOS/timing related.

What's the elevation and ambient temp during these pulls?

Elevation was about 125 ft and temp was 80 °F

My thoughts as well, I'm planning on checking the timing this next week to see if something is off.

Car should be dyno'ing 350-360whp with those mods and torque in the 260s lb/ft, something definitely wrong and especially on such a low mileage.

Got my car on the dyno with Hassan on Tuesday as well.

Mods:
Evolve CSL Airbox
280/272 Shrick Cams
SSV1 Headers
SS 63.5 Catless Sect 1
SS 63.5 Dual Res Sect 2
Dixis Muffler
Turner Pulleys

Car has 83K miles on it and has the big 3 done.

Base pull w/CSL tune: 292
Max Power: 310

Drives a LOT smoother now than it ever did with the CSL base tune.

Finally got on the dyno today with Hassan,

There’s not much in terms of performance shops and dynos around me, the shop I was at has a custom in floor dyno, whatever that means.

Mods:
Turner v2 CSL Airbox
SGT headers
SGT section 1 with 100 cell cats welded in
Stock section 2
Active Auto Gen 6 Section 3

Base pull with a base map from Hassan was:

292whp and 230wtq

Final pull was:

320whp and 252wtq

AFR 12.5-13 a little richer in the midrange

Was pouring rain here today, so the car just wanted to spin the wheels, but it pulls very nice. Big difference over the base tune too. Very happy with the driveability.

Now goin in for rod bearings and vanos bullet proofing in a couple days while I’m on vacation

Why do almost none of you guys get afr logs

Here's one showing afr from another recent dyno run,

Why do almost none of you guys get afr logs

I can get it. The pic I posted didn't have it, but I can get it mine were in the 13 range.

[jet_dogg]

Excellent question.

[jet_dogg]

Yes honestly the best tuner I have ever dealt with. I have met so many tuners that are condescending pricks about valid questions. Hassan doesn't mind answering 50 questions and having a dialog about the car which is huge for figuring out what will work most effectively.

There's a honda tuner I reached out to who is the Hassan equivalent but he's here in the states. Dude charges more and he's a dick.

[gixxer]

Recent dyno from custom multi-map tuning with E50 and AA SC.

Would be interested in seeing what Hassan and Nick could do with the same setup...
