Exactly.
First Time Dyno. What should I have made? What next?
One glace at the dyno sheet and I can tell you it needs work. From the looks at it, it has never even been tuned. I would get a good wideband installed ASAP (I recommend this for any Forced Induction Car) and I also recommend a proper tune.
would you be able to look at a log for me? I have a car that's not running great right now. It seems to run worse once it gets warm and its super rich (big plumes of black smoke when you wack the throttle) I replaced the 02 sensors and plugs as a wild guess. There are no codes being thrown at this time either.
Theee man has spoken. @04sleeper is a legend with the Terminators. He awoke the sleeping giant within my Refire Cobra.
I recommend a proper 04sleeper tune.

What type of o2 sensors did you put in the car? If you did this, I hope you went motorcraft, and not counterfeit motorcraft sensors bought on eBay or Amazon. Also, no big name box store Bosh o2 sensors. They're laggy as all getout. I bought my last set from American muscle. I don't remember the brand but i was having issues getting the motorcraft o2 sensors at the time. I haven't had any issues with them and they're still on my car.
My car with a hurt motor made 454 horsepower with a steggy ported blower with a 2.76 pulley on pump gas with an absolute garbage fuel system. I didn't know what pump setup I had until I tore it apart when I rebuilt the engine. It wasn't fun finding all the garbage that had been done to my car and I'm shocked it made the power it did. It had a canned tune in it and the o2 sensors had been disabled and unhooked.
Now I'm at 700 hp thanks to 04Sleeper tuning with a healthy cammed engine.

@svtioshua pay close attention to what @04sleeper posted. Seriously! He is a renowned tuner here. So do not drive your Cobra any more than you have to while you search out a good tuner. Heck, PM him and let him set you up with a tune! Don't wait. Do it.
Thoughts on the NTK sensors from the local parts stores?
I thought NTK's were the go to replacements if you couldn't find Bosch? I ran NTK's before I went full widebands and didn't have an issue with them.
i used motorcraft... The weird part is it runs bad enough that it should trip a check engine light but dont.
Are you still running the FRPS? Did all of this happen out of no where?
It might be worth posting a new thread.
i am still running the FRPS and it has seemed to get progressively worse. Im going to throw a couple of more parts at it first then ill make a thread.
Pull the FRPS and make sure the diaphragm isn't blown.
Sadly I've been told by friends that off first glace it doesn't look tuned.. Thank you for the advice and I will be looking forward to seeing a new tuner in the next few weeks when my car arrives in GA. She left me yesterday :')
Thank you as well for the advice and tips!
To answer your question from several replies ago about the tune details.. I called the Shop, I asked What Software, How Many Pulls, Timing.. all I got was "We will have the tuner answer that for you when he comes in" and I never got a call back! So moving forward, I will be looking locally when I get to GA and get more advice from local tuners as well. I see @04sleeper is in Dallas, I'll be in SATX this coming late June.
fprs is good. Im buying a set of coils and then If that makes no difference ill make my own thread and consult with a shop of some sort.
I'd call back and ask to talk to him.
I just might. Might get the "he's not in right now". The car was shipped home yesterday because I am leaving the state I am in so there's really nothing that can be done now besides see a new tuner.. So I am taking my L and gonna start again :/
That's too much money to just take an L. They didn't do anything. At the very least you need to post up who the shop is so others can avoid them.
If they didn't tune it I'd demand at least a partial refund. They'll probably stiff arm you but I'd try anyway.
