  1. TSP Stage 1 Tune for the 2017+ Civic Si (Cobra Race Support Included!)

    Definitely! I’m not sure the stock Focus ST I gapped last week is enjoying it though.

  2. SPEC Clutch Proprietary Clutch + Single Mass Flywheel Combos are now available to order!

    Watching this.

  3. 27WON SI sedan exhaust feedback

    I like #2 and #3, equally.

  4. TSP Stage 1 Tune for the 2017+ Civic Si (Cobra Race Support Included!)

    I was SOOOO close to putting LAWNMWR on my plates. I went with NO VTEC instead.

  5. TSP Stage 1 Tune for the 2017+ Civic Si (Cobra Race Support Included!)

    They have both. The MAF is primarily used in fueling calculations.

  6. TSP Stage 1 Tune for the 2017+ Civic Si (Cobra Race Support Included!)

    Has anyone complained about lag with an upgraded intercooler? While the abscence of complaints doesn’t mean there isn’t any lag at all, it’s a pretty good indicator that it isn’t noticeable. As I understand, the 1.5T tuning logic is a torque-based MAP configuration. In this logic the throttle...

  7. TSP Stage 1 Tune for the 2017+ Civic Si (Cobra Race Support Included!)

    Small turbo + small engine + modern tech means that intercooler fill time (and by extension “lag”) is hardly affected. On today’s factory turbo cars, a tune and intercooler are always going to have the biggest bank per buck in power and consistency, respectively. Always.

  8. TSP Stage 1 Tune for the 2017+ Civic Si (Cobra Race Support Included!)

    Having run the TSP tune for a week now (in Slot 3, 93 oct), I can honestly say I’m still impressed with the driveability and power delivery. For all of those worried about the K.control: let it do it’s thing. You WANT knock control to kick in and reign things in, especially when you’re driving...

  9. TSP Stage 1 Tune for the 2017+ Civic Si (Cobra Race Support Included!)

    Well, fill it up and see what happens. If it’s still not quite there, add a single gallon of E85 (to a mostly full tank) and see where it goes. I lived in IL (STL Metro East) for 5-6 years and the gas is meh all around the state.

  10. TSP Stage 1 Tune for the 2017+ Civic Si (Cobra Race Support Included!)

    Mine has consistently sat at .49. 93 oct, no other mods, map slot 3. Even on Ktuner starter maps, I was at .49. It may just be your fuel. Drop a gallon of E85 in if you can.

  11. TSP Stage 1 Tune for the 2017+ Civic Si (Cobra Race Support Included!)

    Yesterday, I ordered my Stage 1 tune and received it within the hour! Keep up that kind of customer service and I’m going to have to buy parts from TSP only. As for the tune, I’ve seen one person say that it’s similar to the starter maps and, to be fair, his opinion has adjusted some, but it...

  12. Stage 1 Tune

    I think you were expecting something else from the tune that no one promised. Yesterday, I placed my order and received the tune file within the hour. I loaded up this morning and from what I can tell there’s a SIGNIFICANT difference on the top end. Yes, the bottom end torque is similar, but no...

  13. Stage 1 Tune

    Did you swap maps? 30wtq should be noticeable.
