I have a 06 mustang gt.I put bbk long tube headers, Catted bbk x pipe, SLP Loudmouths, bbk 62mm throttle body,K&N cold air,Steeda underdrive pulley,Ford racing high performance intake mainifold,3.73 gears, Sct bama SF3 turner running 91 performace tune. My problem is i have no torque what so ever. I called bama for a new tune tought that was the problem. Bama sent me a new tune tried it but still no torque. My car runs fine, no engine problems. I finally called a high performace shop they are gonna dyno my car to see if there is a problem. My question is has anyone had this problem before if so HELP PLEASE.

 

You have no torque because the FRPP intake has 9" runners where the stock unit has 14" runners.

 

Thank you what would you recommend me doing to get some of my low end torque back. Cams???

 

Your long tube headers also reduce low-end torque.

 

Did you do all these mods at the same time or did you test after each one ? 1st thing dump the BBK TB asap!!

 

I did everything at same time except the cold air intake. Why dump BBK TB?

 

BBK (and all other aftermarket) TB's are not as reliable as the OEM style. Dump the BBK and if you want a performance TB go with FRPP although unless you are over 425-450 flywheel hp, it's a waste of money to upgarde the TB.

Intake and headers without cams or revised heads is what is ruining your low down TQ. The Intake is only really a good investment if you have the cams and, ideally, reworked heads to make use of them.

When you Dyno it you'll see this, a much sharper ramp up of TQ and HP above 3000 RPM from the better overall flow. Below 3000 RPM it's going to be less than stock probably.

 

Thank you for the info its been helpful.

 

Just add cams to the mix and retune.

 

Whipple?
