What torque dip?
 

I think the car on stock ecu has enough to deal with the torque dip.

Running on Perrin overpipe and front pipe and Greddy Axleback w drop in filter.

Massive difference after the Perrin parts.

More than enough torque and power to move around w this setup.

Am on 98 fuel but I don't think thats going to make much of a diff.

So does a tuned ECU make the car any much more better?

Opinions?

A tuned ECU will optimize your setup and let your car run at it's full potential

I'm not so sure about that, I still have too see a dyno with a "cured" dip in the torque curve.

This. After my I/E, the dip FELT like it was gone, but in reality, it was just cut in half. Instead of losing 20 ft lbs, I was losing 10... much less noticeable.

The thing is, IF it was possible to correct this throught ECU tune, they would have don it from the factory.
If you analyze the OEM intake and exhaust you'll notice a number of resonators, I think they are there to reduce the issue.

My opinion is the torque dip will always be there unless going FI.

What I meant was the car is not as "torque-less" as most people make it out to be.

The amount of external static pressure in the exhaust system is quite substantial for this car i.e. cats, resonators, inefficient bends etc. Anytime there is a smoother way for the exhaust gases to go with, the difference is noticeably felt.

Sure there is a torque dip but its really not as bad as when the car was full stock exhaust.

I think a tuned ECU will still be good but perhaps try one with an efficient IHE setup first for those still thinking about ECU tuning. The car is a different machine even with a just the changes I have.

Having said that, those with IHE mods and ECUTEK, its probably a real blast.

Yup, should be much more optimised and smoother power delivery

Nothing is as cost effective as a tune for helping make power and helping "fix" the torque dip.

Here is someone's dyno with similar mods as you, the lower run is without the tune, the higher one is with the tune, and this is on 93 octane. Even without the exhaust it will still do more than an exhaust will.

I think an intake manifold may also cure the dip, but I have no evidence of this.

I have yet to see anything N/A "cure" the dip, but it makes a huge difference in the size and length of the dip. Here is my baseline and then Ecutek tune. Sorry for the horrible picture, I only have the printouts. I laid them out so the RPM's match.

E85 does a pretty damn good job of minimizing the dip.

i have the FA20club 93 octane tune and the dip is 95% gone. its there but not near as bad as it is on a factory tune.
