Ive got Wiseco's. No problems yet.

My car was tuned with 91 but I no longer have that option where im living now. Its either 89 or 93. It was a conservitave tune on the 91 so Im sure Ill be safe with a bit of timing increase. I was just looking for a bit of confirmation.

I honestly wouldn't touch the timing if you're only jumping to 93 octane. If you were going to run 100+ octane all the time then you could strap it on a dyno and advance some timing, but keep in mind pump gas does tend to vary a bit so tuning timing to the edge is really not a good idea.

For that reason I'm leaning more towards running my ls/vtec build at a conservative 10:1 compression, that way I can increase timing near the base and a bit through the top rpm to increase the torque curve a little more along the bottom rpm range and keep it singing through the rest of the rpm band. Boost tuning is just like high c/r tuning (with of course the exception that boost compression varies throughout) in the effect that the higher the c/r (static or otherwise), the less timing you want. Increasing timing also increases temp, which also aids in detonation. Just some food for thought.

ill push you dizzy to the fire wall for free 2-3 degrees would prolly be fine but your not going to really gain a whole lot and prolly not worth the time to tune it
