Lets talk turbo lag... or not

Posted a few days ago about the handling differences between the M8 And M1. With your input and alot of phone calls I've pretty well decided on an 09 M8 162, (want that dirt bike nimbleness). I have not ridden either yet hope to in about a week, going to ride alpine and tony grove. If I go the M8 route it's going to get a pump gasser ovs garret set-up. I know lag is subjective to each rider but I'll try to explain. The trx1 I've been riding needs 20-30ft lead time if I want to launch off a cornice. So the questions are what's the lead time for launches? How is the response at boondocking speeds? Is it smooth? Is it below stock power levels on the bottom(sluggish),the same as stock or more than stock. Sorry for so many questions but inquiring minds need to know. Must have raised my daughter right she said to buy both!
