octane boosters?

I guess I left that part out, oops:) I did change the springs and needles to get rid of a rich condition during all driving conditions. I am running a eddie 750 and at first It was running rich all the time until I swapped out the stock needles and springs. I believe I went two stages lean and that's when the issues started. I probably jumped the gun on my post by not doing enough homework but, I know you guys have alot more experience with these kind of issues than me. I really do appreciate all the help and I apoligize for not giving enough info on my problem. Moper, I think you may be right though, I just recently joined a mopar club and we have a meeting on the 17th, maybe I could get some help from there. stay tuned(or untuned in my case for some good results):):)
