I NEED HELP!!!!
 

ok, so i ordered a power pack off of rpmoutlet, the u/d pulleys and a diablo predator, but they sent me a sct sf3 instead, so my question is should i send it back or just keep it?

in all honesty, keep it. its better. lol

I would go ahead and keep it also. I used the diablo on my v6 and was happy, but never heard anyone not satisfied with SCT.

lol, well i already put it on so oh well.. the improvements were kinda noticable, it barks the tires from 1st to 2nd but for some reason if u dont let out of it it just bounces off the rev limiter and wont go into 2nd.. (5100rpm) but if i barely let out of it and get back in it'll go into gear... and also if someone could give me a link that explains in detail what all the parameters mean and how they should be tuned that'd be real helpful

so i gunned it gettin of the interstate on the way to work this mornin and it did the same thing, bouncin of the rev limiter and not shifting.. is this normal?
