I want to put my rev limiter a litle higher. The fire type is thunderbolt IV and is on a 525sc gen 6 engine and actualy the rev limiter is set at 5400 rpm.

Is that I need to replace the electronic module or I can reprogram and change the point of the rev limiter?

who can be reprogram this module?

The TB IV rev limiter is separate component and it cannot be adjusted. You will have to swith to an after market ignition box and rev limiter.

I make a mistake mine is not like this so i dont think it is a thunderbolt IV probably a newer version or a firepower type ing??.

If i can't reprogram the module what do you recomended for a good ignition box and rev limiter?
