Is there any reprogramming that needs to be done to the computer when if you switch from the stock temperature thermostat? I swapped out one in another vehicle and because of the change I throw everything out of whack. The engine started running to rich and stalling out. I had gone from a 185 degree thermo to a 135 thermo. Once I switched back to the 185 thermo all the problems were fixed. Just curious if this was a problem with the H2??

MB, where did you get the heatshield from?

Heat shield was obtained from Summit Racing:

Michael, not to change the subject but in the picture I can see your hood cable with the rubber tube or "coating" on it. Those tend to hold in the moisture thereby corroding the cable causing it to break. Can be kind of a scaring moment...The new replacement cables don't have the rubber on them.

Mine were literally "white powder" inside after they broke.

Where online could I get the new straps from?

As Phil can attest, mine are still in good shape because I spray mine with some anti-rust lubricant I use for everything.

Sorry for late reply. Holidays really messed up time. I would only lower the thermostat temp if I was in a normal condition with engine temp. and went to programmer that would in turn allow Me to run cooler thermo by telling computer you were doing so. Of course at same time getting the benefits of other options of programmer.

The only other way I would run cooler T-stat with stock tune is if You are in a hot temp part of the world and needed the cooler T-stat to try and get to a cooler engine temp and maintain a stock engine temp.
