if u dont have cams, t/b's to go with a chip i have been told that u get very little extra....if u are not going to spend £££ on the engine and chip it alone, is it worth it? the reason i ask is that some ppl have said yes and others no. the reason as to why i would do it would be for primarily track day use......being able to use 2nd for longer would make the issue as to whether to tackle corners in 2nd 3rd easier. i feel that the valver has a distinct advantage here?! i wud also set limiter 200rpm lower than its red line so not do induce too much extra ware, wud this be worthwhile? want a bit extra power but not with undue risk of engine and other problems. any opinions welcome....
