M156 & M159 Tuning Packages with eightysixtuned




That's all I have done right now with the track car. I didn't want to touch the header bolts considering it's 9 yrs old and was winter driven lol.




Surprised there isn't more comparative data on these cars with headers like you see with many other performance cars. The common 4-1 'long tube' headers are not long by traditional standards (considering bore, stroke, rev range, etc..), and common 4-2-1 seem to have excessively large primaries with odd step and primary-to-secondary ratios. And I've yet to see one of the common headers (of either type) that actually merge in the correct firing order.

...literally, you'll have that much power.
















I really like the HPTuners platform. I also like that it supports so many manufacturers, making it a good investment in the long run. If I do go this route in the future, I will be purchasing my own MPVI2 since it supports all the vehicles we currently own. On that note, due you tune other platforms or do you stick to MB only?








Seems legit! *lol*
Ok,, more response, but if bying hptuners i can easily remap throttle to 1:1, then remap it as many times i want.
Yes,, i have knowledge of remapping cars.
Pass on this!
