Wellp driving an automatic might not make anybody less of a man or woman BUT it may make your wallet a little lighter than a manual. Look at it, 9 times out of 10 the L99 underperforms despite being paired with an awesome auto tranny. Some dyno under LESS than 300rwhp. LS1's put down at least 300-315rwhp. So, In order to get that L99 up to par to what it should be doing, ya gotta tune it, which in turn voids your warranty, which in turn makes you PAY for alot of krap that could possibly go wrong due to lack of warranty! Take it with a grain of salt buuuuuut I'l take a manual any day and keep my warranty intact and if I decide to void it (which I will) It will be because im exceeding stock expectations, to just getting up to par to where I shouldve been 34-42k dollars ago!
