With an intake, bama street tune (forgot to change it) borla after cat x and magnaflows catback the car made 405rwhp and 387rtq dyno was done at HK motorsports in North Hollywood CA

Oh and the dyno owner was impressed with how good Bama mail in tune was AFR was spot on!

 

Not bad . Bama knows mustang indeed.

 

What was the AFR? and was the result in STD, Uncorrected, or SAE?

 

Here's a picture of my dyno pull #2 (third pull I got higher tq)

 

Too lean if he's using the factory widebands.

 

Actually from what I have read on the other forums 13.1 is ok with these cars, it's a touch lean but is ok.

 

Yeah I thought 12 to 12.5 was the magic number for these cars. If I remember correctly when I had mine dynoed I was around 12.4 with a Bama tune.

 

This is using the Dynojet Wideband Commander, AFR from the tailpipe and not from the factory widebands. He's averaging 12.7-13.1 air/fuel ratio at the tail-pipe on the graph above... so that's going to be spot on at 12.4-12.7 air/fuel ratio at the factory wideband sensors.

We command .850 lambda. So at 14.64 stoich, in air/fuel ratio terms - that's 12.44 air/fuel (14.64 x .850). These 5.0L's make more power and are safer/less prone to knock at a lower (richer) lambda like .850, then they'd be at a higher (leaner) value like .870+.

The 4.6L's can run 12.7-13.0 air/fuel ratio all day long and make the best power there. These, not so much.

Numbers look great! Thanks for posting up your results. Hit us up if there's ever anything you need!

Those are some great numbers for a canned tune, looks good. hmm i might need to go hit a dyno, i might switch to bama even if I can't get the warranty

although the BBR tune could be great too, just need to find out... maybe I'll datalog, thats free

 

Those are very impressive gains. 91 Cali gas?
