Yes. It is the leanest cylinder and tends to also be on the bank not tested by a wideband while tuning. Motors killed by detonation tend to have a dead #7. It is statistically significant.

When changing my plugs I noticed that no. 8 (passenger's side) had some leakage around its base, so I was wondering about the predetonation correllation with the rearward cylinders.
I wonder why no. 8 is not a problem also. Is there some assymetry in fueling there?

Slight surge with what mods? I would have them done at a good shop. They can tell you real quick if they are close without the hassle of riggin up something yourself. Let us know if you go that route and the cost... I'd be interested.

Unfortunately just testing open flow may not give you enough information. Because these things are fired in fairly short pulses they spend a significant fraction of that time opening and closing, so a slow-opening (or fast closing) injector would provide too little fuel even if it flowed normally when wide open. So I think you'd need to use some sort of pulse train that simulates normal operation in order to test them.

It sounds like a something a tune may address. If it was gone with the Vararam it may be an issue with airflow that the computer "relearned" and it came back. I don't think its injector but I've got little to go on. Let a tuner mess with it and see what you get. Make sure they are in fact a tuner and not a hack, the latter will get you more of what you already got.
