my question here is how do you know if your fuel is quality I try to either get VP racing or chevron non-ethanol supreme(premium) lmk what you think.So after 3 weeks of putting the Phearable 1.5 non-Si through the wringer, it's time for the report card. This will be a direct comparison to the TSP 1 tune I ran for a very long time:
Note: I use 93 octane E10.
Idle: The slightly higher idle speed on the Phearable tune means slightly less shake while idling compared to TSP.
Part throttle lower rpm driving: This is where most of us spend our time. Just taking it easy around town. IMO, this is a wash. Both cars are nice and smooth.
Midrange power: Both tunes excel here. No complaints. Just gobs of torque.
Top end: Similar feel, but Phearable feels smoother on the power buildup (yet a touch more potent).
Fuel trims: TSP's trims are very good. Phearable's trims are nearly perfect.
Knock control: TSP gets a close win here. Phearable's knock control seems slightly more sensitive. Things also took a touch longer to stabilize after a WOT pull. My guess is that Phearable is running a bit more timing?
Now for the final scores. Phearable wins. It's an amazing tune. I dinged Phearable for the slightly higher knock control number after going WOT. TSP got dinged a bit for fuel trims and the lower idle speed. Phearable is also generally a bit smoother. Both are great tunes. Hats off the Derek and John.
TSP Stage 1 score: 91
Phearable Stage 1.5 score: 98
One other note: While I prefer the Phearable 1.5 tune to the TSP 1, there is one caveat. You really need to use quality 93+ (or quality 91 octane with a splash of E85) to keep those knock control numbers down.
