I installed my charger yesterday and the power is nice I must add however I seem to get a pull through all gears up to 3rd then in 4th gear it pretty much seems like my stock truck. From all the posts I have read everyone chimes in about how nice it is to have added highway passing power...WEll I dont seem to have that I seem to have it at lower speeds...Do you thinkI just have to let the ECU adjust more or could it be a pinched vacuum line etc? I have gone over the lines and it appears that nothing is pinched or misproperly placed. Thanks
