I would like some thoughts as to the dyno given the facts below:

I typically lose by 1 car length to my friends stock '05 E55. The car runs very rich in the 4-5k rpm range per Dyno. There is a large spike in boost/blip in RWTQ then it falls. I didn't have boost pressure data on the run. IATs are super high - 1 WOT run in ANY degree weather (even 20 degrees) brings IATs up to 160F and it just stays there, when I run WOT again the IATs fall to 100F under throttle then back to 160F off throttle (very quickly). Swapping out the stock I/C pump made no difference (was told it was not the Johnson C30 pump). Replaced Stock thermostat - no difference in IATs. Car has 10K miles, all service up to date.

• S65 Eurocharged Stg II Dyno
• Meziere Pump (upgraded from stock)
• K&Ns
• Removed Intake Mesh in Intake Tubes

Getting a retune from Jerry and Heat Exchanger - hope that solves it!

Idling and low speed/low throttle iats will be in the 150deg range. High way cruising should keep you around the 100deg range or slightly lower depending on ambient temps. A 30-40mph to 130mph wot pass on the expressway should end up in the 130-140 deg iat range.

Good to know, my IATs seem still higher than that. Just highway crusing is 145-160F and when i go WOT it drops to 90-100F for 5 seconds then back to 160F.

Jerry has my ECU now, hope he can do some magic.
