IMO I don't think it's worth much on a car that doesn't see over 6500, but on a motor that spends a lot of time over 6500 I feel it will show significant gains. But only in the higher RPM range. I wouldn't even consider it on a car running 9.50 or slower. Most guys running that fast will see the higher rpm so making the swap makes more sense on a faster car. The stock ignition works pretty good and we've (and lots of others) have gone pretty fast with them. The DIS doesn't particularly like 2-steps but they work well with the MSD DIS4. I personally don't care much for MSD.
