Accufab 75mm TB, C&L plenum, and a Mac O/R Prochamber.

What I want to know is will I really feel any difference with these new mods? Every thread I have read about the TB/plenum gives conflicting reports. Does it help that I am adding the Prochamber at the same time?

My mods are Flowmasters, 3.73 gear, and a MGW shortshifter.

 

You will more than likely notice an increase in throttle response and your ears will enjoy your new tone

Yes it will be louder. Catted or non catted? If no cats ALOT louder

 

It's an O/R Prochamber. So i'm only gonna feel a little better throttle response with all 3? What kind of HP increase will I see?

Should I get a tune after the install or will I be ok?

 

you'll feel it, wont be night and day but it will be there. the loudness you will notice more than the power increase. the amount of hp you will gain wont really be "felt", but it is there.

 

the main thing i noticed from my tb/plenum was that when u press the pedal, that bitch goes..instead of thinking about it first

 

Cool. Thanks for the responses.

 

Expect to lose some low end w/ the O/R Prochamber. However you are still making more power than stock H, it's just that it moved everything up in the power band.

 

Without a tune those mods will get you 5 to7 HP peak; with a tune 12 to15 HP, maybe 20. If your Flows are welded in to the OEM pipes then adding 2-1/2" tail pipes pipes will get you another 5 to 7 HP.[/align][/align]These are all peak gains, with a tune youshould also get an improvementat higher revsand be able to get usable power up to 5500 to 6000 rpm...[/align]
