Sorry I meant 7427! been doin a lot of reading on here and got mixed up. Anyways what I was wondering about is using a diff spark table outa another bin that is a little more aggressive to play with. Currently using BJLF adv. $Od TPS v251 and was wanting to know how to use more aggressive spark table while tuning ve. Im way rich now so thinkin more adv. wont hurt. Any suggestions for diff spark tables? The more I read on hear the better Im understanding how things work and what their for.
