TSP FE1: a spicy Si

[Savannah@TSP]

One of our passions at TSP is taking a stock, turbocharged car and adding a little...spice.
We've applied this to many of our builds, and are applying it to our 2023 Civic Si as well.
Fun fact: our Si was the tester car during Stage One+ and Stage 2's development.
Check out the progress so far!

These are excellent numbers! Any concerns with reliability at that power level?

Just need some better brakes, any plans there?

We are very comfortable at the currently output now that we have installed our head stud kit.

Just need some better brakes, any plans there?

Work in progress.

So how does tsp stage 1 claim claim 241whp / 286tq but then on tsp stage 1+ they claim stage 1 makes less at 221whp / 251tq and
230whp / 287tq on TSP Stage One+??

What am I missing here?

All Dynos and cars test different. The testing done for the Stage 1 tune was completed with a different car and Dyno than the Stage One+ tune. Due to this, they can not be compared. To remedy this, we provide a full data set with a single vehicle for the Stage One+ tune listing:

192whp / 190tq - Factory Calibration
221whp / 251tq - TSP Stage 1 Tune
230whp / 287tq - TSP Stage One+ Tune

The best way to compare the two tunes is to simply use the differences between the factory calibration and each tune.

I hope that helps clear up any confusion!

Thank you for the clarification. Did your stock clutch slip with the stage 1 non +?

There was some slippage in Map 3 during WOT on our otherwise stock Si.
We chose to replace it with the RV6 FK8 Retro Flywheel + Stage 0 clutch kit as it’s rated up to ~400 ft-lbs and only slightly stiffer than OEM.
