Dyno Results: Conley Performance :{
ok first of all you have bolt on's, lt's, lid, ory and exhaust. 2 hrs is plenty of time just for that. Yes i agree with you, those numbes are a little low however you are on a mustang dyno, those always give a lower #'s. Yes they can retune. until you get a cam don't expect big #'s from just your bolt on's. why did you leave? I would have stayed there and looked at everything they were doing especially looking at *MY* car on the dyno. it's not everyday where your car goes 6k+ rpms inside a building let alone on a dyno. I would have taken a but load of pics... Don't be mad at Conely's get mad at yourself for wasting $450 on a tune for lt's and lid buddy, spend your $$ wisely

Well your reading that dyno sheet a little wrong. What you are reading is the MAX AFR, which is reading at cruse before I step into the throttle. If you have any question give me a call, I will take care of any questions you have. Also you are running 20" wheels on your car, I have seen 420+hp cars loose 25-30hp with "Big" wheels.

Hell, I lost 13 rwhp on a car before just going from stock 16s to 18s. The Mustang dyno also reads about 8-10% lower than a Dynojet, but it is a more accurate tuning device. It simulates the weight of the vehicle on the rollers, so that it accelerates the drums as quickly as the car would accelerate on the street. Dynojets just free-spin.

I agree most people dont realize how much power a wheel and tire combo can eat up.

So long as it runs good at the track, why care? Theres a lot of factors to the dyno number, type, wheel combination and so on. If you want to dyno race, then with 16s and a dyno jet, your car would put up the average numbers for your set up.
Dynojets are a good tuning tool. They are also good for making frameable dyno graphs 
. A Mustang, Dynapack, or any other load based dyno are better at simulating real world numbers. Hit the track and see what the car is running where it counts. However, if you want better numbers for your sig, get on a dynojet and get after it

I think its been established that Conley's has a mustang dyno and that Mustangs will show considerably less power than a dyno-jet.
I have never heard of anyone getting a tune done there, but the guys there seem like stand-up people. We had a dyno day there a few weeks ago, mostly truck. My truck put down 264 RWHP/280 RWTQ. It was disappointing, I was hoping for about 305 HP/330 TQ. From what I've heard, and make of it what you will cause I know they are all different, but if you take your mustang dyno numbers and multiply by 1.15, you should get numbers of what you might expect on a dynojet.
But I also agree with most, that dyno numbers don't really mean much except for braggin rights. Get it on the track and see how she runs.

Stop looking at the NUMBER it made, and instead look at the power delta. They gained power, which is what you went there to have done. Looks to me like they gained a decent amount of power doing nothing more than altering PCM parameters. What were you expecting, to go from 280 RWHP to 400 RWHP with only PCM tuning? 
As far as why your particular car is dyno'ing less than you want, look at all the things others have mentioned -- wheel/tire package, tire pressure, dyno location, etc.

I've heard Conley dyno is stingy on top of the fact its a Mustang dyno.
Ontop of the fact that dyno numbers mean jack
Take it to the track and see what it traps before making any judgements.
