Maptuner / Ibackshift review

[Daniel475]

took the sled to Revy this weekend and all i can say is wow , the Maptuner stage 1 runs perfect and ibackshift clutching was damn close to what joe recommended , if anyone runs maptuner with joes clutching they will be happy , thing flat out rips , ill have to add a little more weight to it but not much , I would say you give up a hair of bottom end response but it is very similar to how quick the stock turbo sled hits on bottom , the mid range to top end is a huge difference over stock , if anyone is considering either of these options they wont be disappointed.

I run the same set up. Maptune stage 1 with ibackshift clutching. I ride at sea level and use the 984 ramps at 29.3 grams! Works perfect!

Did you need to make any other chages to the secondary helix or spring? Or did it stay stock black spring and 40 helix?
