Need some input guys.
Just a quick question guys, when the car is cold(IE) when first starting up the car when it is not up to operating temp less then 150 degrees. The car feels a lot stronger. Once it gets to 190+ degree it seems like its not as powerful. any thoughts. The car has H/C/I/E long tube headers puts down over 503+ rwhp and 460+ rwtq. I also have NGK TR6. It runs fine idles fine and pulls hard but you can tell a difference from when its cold to operating temp. I did just put a dewitts radiator in not that I should make any difference. Btw is a 2005

What you maybe encountering is your ecm using the open loop tables vs closed loop tables. I am just guessing, maybe a tuner could help you.
I am too slow, sorry.
