Any updates on tune/performance ? how are the cheap blue headers working out?

 

Exhaust is the first thing you should do. Helping your truck breathe is key. Headers LT or shortys will be benefical.

 

Read the whole thread... he has it figured out!

headers working out fine, so far. It gets out of its own way, son is happy, more next time I'm down in Fl.

 

Wanted to get your recommendation on what pulley to order from Whipple since you've already been through this. I know you stated you were getting 11.5 lbs with the 4" pulley. My kit from Whipple came with the K&N filter and 4" tube with 4.375 pulley and is supposed to be 7-8 lbs as listed on their site. Have never checked it. They state that for each 1/8" you get ~ 1psi but that was not your experience unless your other mods changed that. I'm guessing its the same kit you bought. I haven't done a single mod otherwise. I am not doing injectors or pump just pulley and custom tune and I definitely don't want to run out of fuel. I may do meth at a later date and a better muffler but not really thinking headers. Ready to place my order now. Your thoughts sir? I appreciate your input! Ted

 

Bump!
