santomen Posted March 23, 2007 Report Share Posted March 23, 2007 I just had a Radix install on my 06 SS a couple weeks ago, I going to change the pulley to a 2.9 and get a custom tune!! The questions I have are: can I have it custom tune before I have the shift kit install or do I need to install the shift kit first? If The tuner should ask: what rpm should the tranny shift at, does he increase the line pressure, should he remove torque management, is there anything else ? Thanks in advance for you help! Pat.

I am no expert but I would get your tranny taken care of first and then the pulley.Your tuner should know what to set the pcm to do in order to shift ok,PM frank at revolution raceworks he is doing my tune for almost the same setup,and he is great to do buisness with Quote Link to comment Share on other sites More sharing options...

Krambo Posted March 23, 2007 Report Share Posted March 23, 2007 I agree with the tranny mods however, I had a STOCK transmission with the Radix for a while and it did fine. I think I may have had a freek 65E but I removed all TM, increased the LP and shifted at 6200, 6100. I don't suggest shifting that high unless you have a cam that makes power over that RPM. My powerband extends to 6400 and then drops like a rock. It is an insurance policy. Quote Link to comment Share on other sites More sharing options...
