Edelbrock SC Stock Tune with Full Exhaust

[Kodename47]

The overwhelming response is negative but the only actual tuner (from Cosworth I might add) has said it will be fine. I'm with him by the way and I've also spent time tuning on this platform. The rest are correct that to make the most from the car you need a custom tune but the car will run fine and not be dangerous on a tune designed for the stock exhaust. If anything it should be more conservative.

That’s my feeling, whole reason why I posted. I feel like the engine should adjust but also think I could play it safe with a more custom tune.

If you still have the stock exhaust, you could always re-install that until you're ready to tune it. That gives you a little safer route as well.

I ran this exact set up for about a month before I put my car away for the winter. It does indeed run really rough, throttle is not smooth, and idle is all over the place. I will be getting a delicious tune as soon as I take it out in the spring.

Way more hassle than it's worth. The tune will be fine and safe. It just won't run optimally. With that in mind, if you're just driving and not beasting the hell out the car all the time it's a non-issue, under light cruise and similar you just aren't making enough torque to do damage. Realistically you have to create more pressure on the components than you do stock to run any risk of damage at all. Plus if you have the ability to log and check, then you can do that and know for sure it's safe and not have any worries at all.

It's amazing how many people think a tune changes massively on a setup like this for different exhaust setups..... The ECU has ways of maintaining fuelling and controlling knock, things would have to be pretty different for it to not be able handle the changes.

I believe the only effect it will have is timing won't be optimized and fuel trims will be adjusted up. I think the ECU supports up to 15% fuel trim adjustment either way if I remember right? Anyone remember? Barely more dangerous than throwing a header on the stock car without tuning, which is no big deal.

It is not.
