Purchased my 2003 M5 in November with a clean PPI and 44,000 miles. Added Shark Injector software a couple weeks later. When sprinting off, 1st and 2nd are full of pull and power. However, when hitting third, the tach will often race up to 6 or 7 with little or no acceleration evident, and if I drop into fourth it will just race right up to 6 or 7 with no pull again. The gear is fully engaged, and if I let off and then reapply the accelerator, the power often comes back. Sometimes it runs great from 1st-5th, but it's becoming more apparent. Is it shift points? Is it the software? Is the tranny slipping? I recently replaced my O rings, but that is all. Any help is appreciated.
+1 on it probably being the early signs of clutch failure.
If the clutch is starting to get ready for replacement and you happen to get on the power a little too early during a gearchange, it will easily slip and so revs rise rapidly without much go. If you then get off the power and the clutch hooks up properly, full acceleration would return unless the clutch is really on its way out in which case it'll still slip.
