Hi guys
I was excited last week took the car to the dyno to see what result happened from my changes to the car.

ok, I'm down 16 HP and 70 lb of torque!
It doesn't make sense!
The car runs beautifully, pulls strong now all the way up to 5800 rpms! It is a blast to drive. It comes out of the hole like its on fire now.
Why would I be down?
Thanks for any info
Ok for the record temp and humidity for pretty similar!

If it were mine, I would have gone with around 10.7.1 Compression with the Aluminum heads & The XE284H or 285HL.
76 jets are a bit fat on a standard 750dp. IMO, I'd start off with 72/80-82 & go from there, I ran 74/82 in my PF 750dp, of coarse yours may very.
