If the tune is good and there is no detenation could we add some more or should we leave where its at. * Adjust the timing with a simple twist! * Advance the ignition timing up to 9° * Select a step retard up to 18° for nitrous use * Twist in a boost retard from. GM > Engine > Spark Control > Spark Advance. This steals some of those hot, expanding exhaust gasses to help spin the turbo a little faster. During WOT testing, actual spark advance should be recorded as well as knock sensor signal, if available. 7 LS1 made by Edelbrock. The LNC-2000 is designed for use on all GM LS series engine applications LS1, LS6, LS2, LS3, LS7, LQ4 and other Gen III and IV GM V8 applications. I have not changed the oil since I first started the engine up. Also, for decades racers who 'locked out' their dists found as a side benefit that they had a smoother & cleaner idle. That was the maximum boost and timing that pump gas would allow and still be safe. Figure 20 shows the camshaft in the advanced position with the intake tappet open much further at T. I would expect the computer to advance/retard timing smoothly with engine acceleration, not jump back & forth. Valve Overlap Lobe Separation is not the same as valve overlap either. 33deg at 0vac taking out 1deg of timing per lb of boost.
