Dynoed yesterday cehck out the graph looks like im running way rich..What do u guys think.. Also lol the dude accidentaly hit the brakes on the dyno.I thought the truck was comin off lol smoekd the crap out of my tires..

 

WOW. Your A/F is well below the chart. It's definitely rich - but some like that insurance.

What mods? ...that graph looks more like a stock L graph.

 

99´ Red Lightning
Mods- 3/5 drop, Airaid CAI,4# lower pulley, Billet grille,Smoked taillights,
02' L Wheels,Tonneau cover,JDM catback,2 gauge pillar pod, Autometer Lunar gauges,Predator..
Times-13.4@103 60'@2.0 lol

 

You may be a bit low for those mods on a '99...but all dynos are a little different.

Best to have the tune rechecked. Lean it out a bit more, then go dyno again. This time, don't let them hit the brakes

 

YA i just walked out to the beast and leaned her out alittle smudge...Im going to have it tuned by coastal here in a few days..HE tuned my buddies 03 cobra and did a great job at it. The cobra only has catback, x pipe no cats,CAI, 2.8 upper, predator and pulled 405hp 410trq on a mustang dyno.Not bad at all.

 

355HP for those mods is pretty low, most likely due to runing so rich. Get that A/F up around 11.5 to 12 and you'll be making closer to 390 HP.

 

Ya those are the numbers i was looking for yesterday but runnin that rich makes it sorda hard to have high numbers. Im also going to buy a 90mm MAF this week. Along with have it dyno tuned..

 

You cant go by dyno numbers. I have said it befor and will say it again. A dyno should be used for tunning and maybe comparing before and after numbers.

I dynoed on a munstang dyno about the same as you did with my A/F in the high nines and then went out and ran 12.6@107mph all day long the next weekend.
