Hello all. This has been asked more than a few times, but, what is the easiest or cheapest way to squeak out another 20-25 hp from the CSVT? I already have a K&N drop in, otherwise engine is stock. On a similar performance note, can the rev limiter and fuel cut-off be raised with a chip or other? I sure would like to rev another 500rpm. Thanks.
