lumpy acceleration

I've been noticing that when you feed the power on in a slowish but steady way all the way to just before the red line I notice a couple of 'steps' in the rate of accelaration (and no it's not the turbo coming in).

I noticed it to a lesser extent before fitting my dual port wastegate. They are not significant lumps or steps and you don't notice it when you floor it. Just wondered if this is normal or if there might be some timing/fuel/ignition problem that can be addressed. Other than that everything else appears normal.

Cheers.
 
Hi Scott,

My '88 S does the same. First step is at around 2k rpm (it really seems to hate the revs being anywhere around 2.25k), then surges again on to around 3.5k, where it seems a bit flat, then really kicks in from 4k on to the red line.

Apart from all the usual age-related fettling (throttle body, AFM, vacuum hoses), there seems to be very little I can do on mine to improve, other than consider a chip. But, I haven't got the plethora of playthings you've got with a Turbot.
