Renntech had no unhappy customers that I could find on those same forums.
Evosports package with the ECU program is $2,850 if I remember right, without a dampened crank pulley...
now I see they have a dampened pulley upgrade for $999. Or just a pulley kit for $1,999 without the ECU program.
The Renntech kit is only $3,000 for the Crossfire SRT-6 and it comes with a dampened crank pulley along with the other pulleys and ECU program.
So that's why I just chose Renntech.
Evosport does have the dampened pulley now and there kit includes all the pulleys. The dampened pulley that the SRT6 comes with from the factory is the band style, which has proven to be useless in any dampening abilities. So Evosports non-dampened pulley would not have added any risk. Evosports new dampened pulley is the suspension type design which is a very effective dampener and gives the engine much better imbalance dampening than the factory dampener. I assume that Renntech uses the same design as Evosport (2 piece suspension style)?
