Ken B said he will not do a tune with HP tuners because he is scared that the customer will make a change in the tune that hurts the car and blame PBD.
I purchased the HP tuners cable and credits last week and had the car tuned for the headers and cat deletes.
Baseline Whipple tune with the 3.625 pulley made 710 hp and 552 ft lbs.
With simply turning off the safety features from the Whipple Flare program, we made 786 hp and 592 ft lbs and picked up and extra 2 lbs of boost. (Whipple overload limiting only allows 45% throttle. When this is turned off it goes to 85% throttle.)
My tuner didn't even have to do much with the Whipple tune other than tweak some drivability stuff such as power enrichment and torque tables.
HP tuners also allows you to view knock by individual cylinder, which is nice!
Data log showed zero knock, 18-19 degrees timing with the Whipple tune wanting to add 1 to 2 degrees more. Tuner advised we could safely make another 30 to 50 hp more, but I felt no need to push it further as it is my daily and rides on streets tires.
Sunoco 93 octane.
I'd recommend using HP tuners as you can tweak the base Whipple file and then retain the ability to use the flare settings as needed (I.E. power by gear etc.)
