Get yourself a sample of fire sleeve (the orange stuff) and slide it over the adapter/sender. If the headers are in fact influencing the sensor temps, this should solve that. If not, you know it's another factor.
No. Not on a street application. For a track car or dry weather only car it's much less of an issue.
It's definitely a long process, taking many days. 4 weeks including shipping during the slow season and longer during the busy season.
I think most of the complaints are from people that have never used the service before and don't know what to expect. Application is difficult to precisely control so there can be overspray on v-band flanges. It just takes a little time to clear off; it's not difficult. There are not nearly as many complaints as there are happy customers. Half of the headers we sell, are bought with the Swain Tech option. With our Vektor Performance headers, about 80% order with the Swain Tech option.
Thanks for the heads up. We are scheduled to make web-updates soon and that is on our list.
Gotcha. I'll give the fire sleeve a try.
It mostly just seems odd that the temps jumped so drastically immediately after the header install. It seems most likely that something is being affected... hopefully it's just a false reading off the sensor and insulating it can take care of it.
