hey al,

I have an 05 gsr that was mail in flashed (stock) with boost taper but before you offered the 2 step launch. If I add the following would I need a reflash to drive the car safely? I plan on keeping the car with these next mods like this for at least a year.

1. drop in K&n
2. high flow cat
3. mr bov

Then after a year or more add a fuel pump, cams etc, which I know would require a reflash or custome tune.

 

no - you can just go with the same tune
