So I'm do some general maintenance at 75000 miles such as upgraded timingbelt, waterpump, and possibly a new clutch. I've been thinking about getting a j&s v2 to get as detonation free as possible. I've also been considering an efi pms instead of the others due to the atts. Now if i get the pms do i still need the j&s. Also, what is it that causes that power lag in the mid rpms. you give it gas but dont really get any power. Is there a cheaper way to get rid of this other than the pms or a handful of piggybacks. I know absolutely nothing about tuning so as much info as possible would be great. Oh and remember that i have farely limited funds and need it to be very reliable and longlasting.
