Spot opened up so decided get the car dyno tuned. Managed to squeeze out 306.06hp and 304.67tq on 91 tune with very little mods. Mainly got it tuned to get better drivability.

see below graphs for before and after

those are some strong numbers at the wheels, and on 91 too.
Thanks. I was a bit surprised too, but this tuner is extremely knowledgeable with these cars and knows what he is doing. Just wanted to get rid of the part throttle lag I was having and modify the fan settings, etc. The car scoots and runs very well. Excited to take it on a canyon run this weekend. I am glad that finally got the car tuned properly.

Would love to have a mod list to go with this graph!

This car doesn't have any engine mods, Just parts of the exhaust was replaced.

Air intake silencer delete
Ford racing headers
OEM cats with ford racing cut and clamp x- pipe
Borla xr1 exhaust

If your car is not having any driveability issues, you don't need to tune it. Tuning a stock car with just an exhaust mod is pointless. I just wanted get rid of the wonky factory throttle lag casued by charge motion valve, adjust the fan setting, check the fuel.

I'm not a fan of the factory throttle mapping on these drive-by-wire cars myself either; same goes for my Focus ST. Fortunately my new-edge Cougar is as analog as they get, which is a must for track use if you ask me.

Are those long-tubes or shorty headers? I've never wanted to commit to dealing with LTs myself, but it seems most will tell you that the shorty models don't do much for performance over OEM manifolds.

Those are some terrific gains for basic exhaust work; bet it's a riot to drive. Thanks!

They are shorty headers. I believe if you have a hand held tuner or date logger, you can get a mail order tune to get rid of most of the issues and be more affordable. I never invested in hand held tuner device for this car and dyno tune route was just easier for me. Yes, there is a big difference after the dyno tune, car drives much better.

I have a good local tuner who did my track Cougar, so if I decide to go with a tune that would be the route I take. He's of course an LS specialist, but has plenty of experience with modular Fords as well, so I have faith he would do a fine job. You're giving me lots of ideas, haha - thanks!
