I have a 4.10 geared, K&N intake, MO's tuned 03 marauder. What is everyone's thoughts on Throttle Body Spacers and thoughts on pulleys. Does either make a significant difference in power without effecting anything else?

I have heard that UDPs are not a good bang for the buck. I've always thought of TB spacers as gimmicky as well.

Pulleys make about 10-20 hp difference. Idle may need to be raised a bit to keep the battery charged. Make sure and use the "good" ones and get them installed right. Spacer is a waste of time and $$$

I have the Steeda UDP. That's all it is, nothing more. requires a shorter belt, too. I believe it slows the accessories down 15% IIRC. Also, yes, I had to add 200RPM at idle but it is not even significant when you are driving. Between my gears, programmer, CAI, and UDP I really like the feel. My latest mod was billet control arms and that firmed up the rear end and made snappy upshifts that are rock solid. Boost is coming as soon as the right kit is available.

thanks everyone for the input. I appreciate it. I'll skip the spacer and consider the UDP. I like the thoughts of a little xtra HP.

I have front and rear control arms coming from ADTR and my next mod I'm looking at control arms for the rear.

the control arms from ADTR are for the rear, upper and lower. there is no upgrade for front control arms. Addco sway bars would be an upgrade front and rear as well as a watts link from metco, or the che brand sold by Sparta here in vendor section
