Tecnosquare came out with a reflash for the spec-v but it is the most retarded thing ever done to our cars. Basically it is the same price as the cobb reflash for the wrx and sti ($600 or so) and all it does is raise the rev-limiter from 6300 to I think 6700. No net whp gain or different maps for FI specs.

Cliff Notes: Tecnosquare can suck a big fat one for their work on the spec-v

In addition it is easier to swap a VQ35 into a sentra than it is to crack the Ecu
