Dissapointing p1x numbers

[wazslow]

If this is an MT-82 car, 1:1 is actually 5th gear I believe. That can account for some discrepancy. Not 100 wheel or anything, but some.

15-17 MT82 - 5th gear is 1:1
18+ MT82 - 4th gear is 1:1

At what rpm was the car dynoed to? The run could have been stopped short

Supposedly 8k and built boost to 8k but only made power till 7850

Get your dyno sheet first. What size injectors?

Dyno graph (and dyno file at least if dynojet which allows you to view in their software at home) will be a good first step. Even better if Air/Fuel and/or boost were logged on the runs. Beyond that, you really need to log timing and the fuel or more. That can be done on the street. You cited a timing # but I presume this was not verified as actually achieved in the run and at what RPM. Maybe something goes awry and your achieving only 10 degrees at the top end. 10 degrees could be 100hp. It's all got to be verified and not just 'I know or was told the tune calls for 20 degrees'

I mean if jackson1320 is making 892 with a gen2 on a carb legal kit. Well thats only a small discrepancy of 170hp. Lol. Wtf? All the nut and bolt stuff is done. I'm heavily leaning towards it being a tune issue. Going to try to get my hands on this dyno graph today and post it.

I’m a firm believer of taking what people say on a forum with a grain of salt, specially so when it’s hearsay. Come to your own conclusions and results.

Back to the situation. So clutch isn’t an issue, but track might not validate your numbers because it’s a manual, and unless you really get after it you won’t see results and therefore seem like there isn’t power being made. Last option is to find a coyote specific shop, one that has dynoed several cars, even more helpful if it’s people you know. Don’t matter if they were whipple, vortech, or VMPs. As long as it’s stock motor on E85 you can use that to compare to yours, so take it to one of these shops and put it on their dyno.

I’ve seen randomly low numbers on a dyno. Gotta make sure you either pull fuse or the plug on drivers side fender. Also drive on dyno a bit for car not to trip out. Or tires spinning

1300's

Sounds like you should be making 850 PLUS. Take it to a different dyno.

So finally picked up car and confirmed it is a mustang dyno

since it's an Eddy, he will have input your car weight in order to provide load. Ask him for ALL of the input variables.

Stingy dyno.

Stingy dyno.

You'd think being a fellow Mustang it would share the love, but NOOO.........

my counselor said lying and inflating matters was unhealthy and ultimately destructive.

So the long and short is, he couldnt supply me with a graph due to some equipment error.
However did give me a basic print out specifying weight is 3600, HP at 50MPH 12.50, 716.2 @0 RPM/155.6 with WCF 701.2. Car is way faster than it was before but the drivabilility at cruise is horrible. 60-70mph almost feels like ignition is breaking up or fuel supply is intermitten. Either have to mash the gas or let off completely and drive slower. Around town it does great. Wondering if the ford adaptiveness will clean up that problem or if its a issue that needs to be handled by the tuner. The saga continues!

Maybe I missed it but who tuned this??
