Seems that auto sucked up some power.

why do you say? his best before was in good weather. also he was shifting early and not crossing very high.

They always suck up more rwhp. I just saw two gen v's loose quite a bit of rwhp when swapping the m6 out. Just par for the course.

I agree it sucks up some power but its faster. I expect some good numbers when it cools down;)

Congrats Great pass.

Dose he like the 4l80 swap? Its the best mod that i have done. best 60' 1.51 with 3.45 gears and i have lots of room for more H/P or lower gears traping at 5400 rpm in 3rd. and with the 3.27 was traping at 5200 rpm

yes so far he likes the 4l80. last night was the first time out with the 4l80. he was shifting low and feeling the car out. we were thinking about going to the 3.90 gear but we may hold off til we get some good weather. i'm not sure what he crossed at because we didn't log it. it will be logged next time.

update

Nice runs.

Thank you. it's still hot here in south Louisiana when the weather gets better I expect to see some really good #'s:thumb:

If he made 726 with the M6 that has to be at like 650 now bc that mph is low.

I agree the mph is low. we are going to see if we can fix it.

very nice!
