like the title say my buddies has a 08 civic si 4 door he has hondata flash pro curently stage 1 stage 2 is on the way the car with the tune that comes on hondata and loaded on the car for stage on it runs mint now it also has tunes for stage 2 and 2plus now when we put the stage 2 on the car should he take the car to get tuned even if it runs fine how it is the car also has buddyclub race header and full catless 2.5 inch exhaust and injen short ram air intake. any input would be great also those who know the hourse power this should yeild just let me know thanks in advance

 

Only good things will come from having the car tuned.

But if it runs good and he is happy why mess with it?

With a tune you will get more power and better fuel economy. The tune may be running rich as a safety margin because it is generic. He already spent thousands on the charger, why not go 500 more and dial it in?

I'm not up on the ct kits but I thought about 300whp was max with a supercharger but more like 250-290whp

Have they ironed out the problems with the cold starting with the ct superchargers?

 

get it tuned. i gained nearly 10hp and tq from a tune with just bolt ons and i was already running a base map. on fi, it will only yield more power since everything is multiplied in terms of power add ons.

 

its been resolved. it was the cranking fuel.
