was thinking of getting TB/Plenum for my 99 gt, it pretty much staying stock except for the 3.73's and O/R X-pipe i am getting it tuned so i would like to know if its worth getting the TB/Plenum before i take it for the tune? if so what is the best bang for the buck and i dont car about looks...trying to keep my spending to a minumim

 

801 posts and you forgot the valuble search tool & stickies?!
j/k... nothing personal.

they all make similar numbers... accufab seems to be the best. without f/i no amazing difference though. if you aren't planning on much more for a while i would get the tb first & then tune it.

 

like 4 whp gain not worth it. for an accufab tb and plenum u are looking at 500$. even with FI it ain\t worth it unless u got heads and a lower intake. where the air is force in the extra 5-10 mm don't make a noticable difference

 

you obviously don't know. before and after of when i put the accufab on my car WITH a blower was 354RWHP to 360RWHP. i HAD the MAC on there first and the car did 362RWHP, which was a smidgen more than accufab. the guys at the shop offered me a spare accufab at cost so they could put the famous accufab to the test. it does look a lot prettier though.

the only noticable thing you'll get is better throttle response.

 

mainly tb/pl is for a good throttle response more so the horsepower

tb/pl throttle response>HP

 

yeah, but the problem with the throttle response, is it makes you think you got a lot more power than you really did. if i didn't see my before and after dynos with it, i would have thought i gained like 15RWHP or something retarded. it definitely FELT like more power than it really was.

 

lol well its suppose to.... thats the point of throttle response..its going to hit harder faster lol...u shouldnt expect hp out of them.. just a better hit the gas and go feeling

 

yeah, but you know how people on here are. they make it seem like it gives you massive amounts of power if you're running a blower already. so i always have to sing it loud and sing it proud that those people are full of shat.

 

I did the proffesional products 75mm throttle body/upper plenum combo off ebay. The throttle response certainly got better and at higher speeds(90mph+) I could tell a noticeable difference. The car didn't seem to fallover as much shifting into 5th around 130 either. The only thing I don't like is the hanging rpms.

 

yeah understandable lol
