I have a 2008 Auto V6 mustang and ive already put in a BBK CAI, Throttle body , and the Throttle body spacer. Ive been driving around fine without a tune and everything has been going good. I recently installed the Pacesetter long tubes and the Pacesetter shorty off road h-pipe. And now my engine has a hard time being in idle, like it will drop to 250-500 rpm and just bounce like if i had Cams installed in it. I have to wait about 5-10 minutes every morning before i can drive it because it has a hard time going if i dont wait. I know i need to buy a tuner and tune for it, but since i cant buy that right now can i do something else to help it out, like changing spark plugs or oil filter?

How long ago did you install the BBK throttle body and spacer?
Is your V6 F/I (force induced) or natural aspired? F/I, supercharged, turbo etc.
I've read several post where people encountered issues after installing the BBK TB and/or TB spacer. From what I have read, they are not beneficial if the car is not force induced.
Does the pacesetter long tubes and shorty off road require a custom tune?

Ive had the Throttle body and spacer for a couple of months without trouble. Its a natural aspired v6. Neither the longtubes or the hpipe required a tune, Though it is recommended, What i figured was i would buy all the bolt on parts and then get a tune for it all.

Sounds like a lack of back pressure due to the long tubes and off-road H-pipe... BTW, you like how that sounds...?

ZombieHuntr

lack or backpressure cause of the good stuff. Not mention with all that, the car is probably reading some really f'd up A/F ratios causing it to do that.<-- SEMI-educated assumption.... The tuner should be your next mod. You got the car breathing pretty well, now teach her how to breathe properly! lol.....

When I first put it on it sounded amazing. Had a nice deep rumble web using muffler deletes. But I put on the stock gt mufflers because it was obnoxiously loud lol. The gt mufflers make it sound kind of like a ricer once it gets passed 5000rpms so I'm gonna invest in borla tourings after the tuner

Haha yeah. It sucks I buy things to make it better but it turned on me. Yeah I'm ordering the tuner tomorrow. What can I do if I can't find my ECU 4digit code for the tuner?

I've heard no cats with an array of mufflers and IMO it still sounds ricey...

With the long tubes and deleted cats I think you need to adjust the tune. The computer is looking for information from the sensors that aren't there now.
