i have a 98 12v with a #5 plate starwheel maxed and the brass elbow... i tow a lot with it and the EGTs get hott going up hills bout 1200F depending on the hill and the load... whats a way to lower the temp without downsizing my fuel...also it seems to build the most power only while in overdrive 45mph and up how can i get all that power sooner?? thanks....

 

If your converter can take it put a lockup switch on it.

 

Little timing may help. Some exhaust would help depending on what you have.

 

Is your pyro probe in the manifold or the down pipe? If its in the mainfold then seeing 1200 is not that bad. I used to sustain 1450 on my old 97 towing long hills, that truck has over 400,000 miles now on the original injectors and pump. Never hurt anything except transmissions. I see 1400+ on my 02 every day.

Like said before some timing would help. Bigger exhuast if its still stock.
