Fikse...To a small degree, my initial feelings also.......but
My 457Hp was Pig Rich in 95 degree weather and uncorrected
The A/F ratio was close to 10:1 and I never got the ECU re-programmed f/Klemmann before the TB install. When I study before/after..a few thoughts
1.) 25 degrees cooler(today) on FI motors is worth 20-25hp alone!
2.) A/F going f/10:1 to 12:1 is probably worth another 15-20Hp
3.) That means the TB realistically is giving me 30'ish Hp(that's believable!)
I knew going in I would see a Huge jump because my new K2 w/o being re-programmed was showing only modest gains.
Most on the forum are 470hp - 500hp "tuned" --w/K2...I was @457 "untuned"
Yes... the track will be the proof - I'll be out there the first chance I get.
I'm sure there are a few sceptics...but the law of engine physics does
suggest this to be at least possible. I'll post graphs as soon as I have them.

Hello Ken...I also have some probs adjsut my A/F to make the car to run more efficient...
Are you running 12:1 WOT ???
Can you find out all you A/F ratios across the RPMs range ???

Since our cars do not use a mass airflow sensor to monitor incoming airflow, in theory we will run leaner if more air is added and fuel is not. I don't know how much correction can be made by the O2 sensors, but you should be leaner with more air getting into the blower. Boost is unchanged so the MAP sensor will tell the ECU to not change the fuel trim.
