For those of you running any kind of piggyback on your 335d, have you noticed an increase to your baseline EGTs. Leaving aside hard acceleration and regens I think I was running avg. temps in the high 400s. Now it seems to run consistently in the mid 500s. Clearly I need to learn how to use the logging function in torquepro.

Here's some data with EGT's for stock and a couple settings of the JBD. This was with full emissions equipment in place:

Here's some EGT's for Evolve remap + various JBD combinations. Still full emissions equipment.

http://www.bimmerfest.com/forums/sho...8&postcount=49

And then some examples of Evolve stacked with JBD on low and using H2O/methanol. Again, full emissions equipment.

http://www.bimmerfest.com/forums/sho...1&postcount=62

One important thing to note is the above data was for short bursts of full fueling. Sustained levels (like in a 1/4 mile pull) would produce higher EGT's. The water portion of the liquid injection really helps control EGT's...

Removing the exhaust bottleneck allowed for even more aggressive fueling while maintaining even lower EGT's. For the back to back 11.8 sec 1/4 mile pulls I was logging peak EGT's of ~1100-1150F if my memory is correct.

High 400s idling and light cruise @ 85 degress ambient air.
