i am mixed on it....i can see both sides of this arguement..however i have been doing this to my gsr tranny for years and it shifts like butter. while you may not depend on it to set any records it is still not bad as long as you know what you are doing. i wouldnt say its a skill but you gotta admit there are alot of ppl that cant even master the quick 1-2 or 3-4 shift..thats the easiest **** ever! if you can hit a 2-3 shift with out lifting and gain a little time in the 1/4 why not do it? after all..you paid all that money to mod your car so you could get the best out of it. im all for "power shifting" if **** breaks then it was obviously too weak and was meant to be modified so it wont break again!!
