swamps hvhf idm..

[Nodge]

Just put a swamps idm on my bone stock 97 with 70k miles.
Immediately noticed a quicker start and smoother idle.
Will install the other two tomorrow.

I just put a Swamps HVHF IDM on my bone stock 99 7.3. Throttle response is a little more crisp and easier starting too.

I've had one for a few years now. When I put it in at first I tooled around town not really noticing any difference. On the way home and I called on it to merge onto the interstate, it came to life. It pulled hard up to and over the 3000 rpm range where the stock one would start to slack off. just my experience.
