I'm looking into putting the skunk2 IM on the LS and I wanted to know....what do you guys think about it??? Is it worth it ...the car has intake and exhaust and thats it as far as the motor....will I need a dif. TB ????

 

I've got a S2 IM on my LS, I like it but I haven't had much time to test it out as I promptly developed radiator issues. I can post more next week after I've gotten to drive it a bit more. and I've got my stock TB on it for the time being.
I also added a new fuel rail and fpr while I was at it along with a new set of stock injectors so I think that's enabled me to keep the mid range tq that others were reporting losing. do a search for skunk2 and you'll find some of the recent discussion of that IM. HTH
