Purchased a used A&A supercharger kit with a 3.4 pulley on it. Purchased a 3.8 pulley to reduce the boost. Last night I did some reading and I pulled the trigger on a Snow stage 2 Meth injection kit thinking I could run the 3.4 while giving the engine a safer amount of octane at the same time.

Frank from A&A responded to my question by saying that he would suggest running a 3.6, the 3.4 would be pushing it.

I have a completely stock ls2, and would like to drive it as a daily driver and keep it safe as stock.

Has anyone else gone from a 3.8 to a 3.4 using meth on completely stock ls2? Any regretes?

I kinda don't want to search for a 3.6 pulley to put on since I just bought this 3.8...But I might have to I guess.

Or would I see enough benefits from running meth with the 3.8...over a 3.8 without meth to justify just keeping the 3.8 on.
