04 GT
Good morning everyone. I recently became a horsepower fanatic. I bought an 04 mustang gt for 7K with only 32Kmiles on it. I believe car sat for a while because HP was way low and rusted. I made changes I put K&N Intake, 40's Flowmasters, BBK 86mm MAF, 30LB Fuel Injectors, Accel Coils ,and NGK Iridium Spark Plugs. HP is not too bad now, however now my RPM is at like 600 at Idle after the Mods. Any ideas on how to fix this issue or is it normal for this to be like this? It doesnt Idle rough or anything and has quick takeoff but takes longer to change gears at higher RPM. What should I do.
