mods in sig. debating on tr-55's or tr-6's. i rarely ever use the nitrous anymore. upgrading to long tube headers real soon. any one mind offering their sound opinion? Thanks!

 

If you are not going to have a power adder then I would go to a TR5

 

Useually the standard rule of thumb, if your near 400 fly wheel hp, putting in TR-6's regardless of power added is considered a good thing. I ran TR-55's last year and I ran REAL lean. Going back to the tr-6's yeilded a much cleaner plug.
