Suppose the group buy deal that troyer is putting on for E -fans and Pullies is on my mind...

My truck is VMP tuned (mail) for headers/cats/exhaust and intake

since these upgrades dont directly affect the air/fuel ratios would it be necessary to get a retune?

-thanks

 

E-fans and/or pullies don't generally need custom tuning, but I'd give Mike a call and run it past him. With both, you'll probably need to raise the idle a little bit.

 

Thanks I will do that.

Have no idea what making the engine run "easier" will cause to happen anywhere else. My guess is not much, but I hear guessing is overrated.
