tunnel ram and 750 eddys

I'm all about cheap. The eddys are my cheapest route. Will have less than 300 invested. The 850 will cost 300.00 plus used then 30 to rebuild and probably at least 100.00+ for linkage. The dominator will be 450.00+ used and 60.00 for adapter. I already have linkage and fuel line for the eddys. Just wanted to know if they will out perform what I have now when tuned in. Thanks for all the input.
