Does anyone have the Evolution powersports stage 3 tune in? Wondering how it is doing. Have herd about TD but not EVP .
 

I can tell you that all the stages work great from EVP and 634 trouble free miles and you want power? Stage 3 for trail use with Premium fuel.

Stage 4 is 50/50 race fuel and premium.... HANG ON!!!!

WhT do you run for clutching ? Just weights with spring adjustments? Stock belt?
 
Thunder Products kit for the sidewinder

Weights, primary spring and glide washers. Secondary stays the same. 8JP stock belt with good luck so far.
 
Started with stage 3 worked great and now on to Stage 4 on 91 pump as they have reduced boost from 16# to 14.8# have ran stage 4 for 400 miles so far and works great.

Wonder why they turned the boost down? Maybe because 95 is hard to find at stations ? Wonder how that effects the HP ? They were claiming 71 hp gain with stage 4
 


I think it has more to due with maxing out the duty cycle of the injectors. They likely found afr on the lean side at anything above 15 psi.

Testing Stage 4 we found out the stock injectors were maxed out at 16psi.
