2018 Jaguar F Type 400S AWD Tune
Hey F-Type Fam,
Recently upgraded the Crank and Super Charger Pulley, and installed the Mina Gallery Intake. I took my F Type to a Jag/Porsche specialty tuning shop. After a day or two on the Dyno, they gave me a call that the car is not performing as expected, but that the tune was successful and all the curve's/numbers look good. They performed a leak down test to rule out any obvious loss of power but could not find any "smoking gun". Anyone run into this situation before, I feel the power gain from the upgrades are much lower than I have seen discussed during my research. Specifically the Torque.
Tune Results: Wheel
Base - 323HP/340 Torque
Tune -371HP/344 Torque.

Agree the above: Factory intake is made with taking in count of shockwave pulses (eliminating them) when Mina Gallery is more sound / noise orientated.
Shockwave pulses slow down the incoming air, basicly you engine is not breating well.

Bypass valve stuck open or cracked. Or they left the torque limiters stock because they're scared of the transmission. That torque number is what a stock car makes with just an intake. Something is bleeding boost or holding back throttle.
