PDI Air intake manifold

So far so good, engine seems to be a bit quieter and runs much smoother. Engine temp has dropped some and I have a bit more throttle response. Still not totally on board with these new motors. I miss my old E model cat, but I’ll probably end up getting a tuner from you all too,eventually. If I don’t delete it first!

Bad cord I hope

It’s not working. I’ve spoken to Robbie on several occasions and he thinks it’s the power cord. I just had to spend $50.00 to get a new cord overnighted to me after spending $3,700.00 last week?

It has been great!!,I am

It has been great!!,I am averaging 6.5 mpg loaded.before the new intake I was averaging 4.1 to 4.7 mpg, and I see a massive difference when I am pulling up on the inclines. Cant wait to combine it with the big boss performance tuner
