How the FlashPro will perform on a stock Civic Si ? The answer is superbly!

With a 100% stock  Civic Si Turbo you will benefit from:

•  27 HP and 40 lb-ft torque
• Improved turbo spool
• Raised boost limits
• Better throttle response
• Better mid range power and torque
• Removed speed limit
• No change in part throttle fuel economy
• World class datalogging - which will teach you a lot about your engine.

Base map:

• Dotted green line stock Si. 205 hp 235 lb-ft torque.
• Solid green line Hondata +6 psi reflash. 233 hp 258 lb-ft torque

 

+ 9 PSI calibration

The supplied  +9 psi calibration (light blue line) is capable of generating 272 lb-ft torque.  In our dyno testing we found the stock clutch beginning to slip. The Dynapack dyno is very hard on the drivetrain and is more likely  to cause slip than street driving with stock tires. Our road testing to date has shown no clutch slip with the + 9 psi calibration. We recommend using the +6 psi calibration and an upgraded clutch.

Mitsubishi Turbo Si calibration

Stock cat, intake and exhaust. 93 octane.

Clutch recommended

• Dashed green line stock Si. 205 hp 235 lb-ft torque.
• Dotted red line Mitsubishi turbo. 250 hp 275 lb-ft torque
