Okay I am at 125,000 miles now. I bought the car about 10 months ago at 110,000 miles. I was wondering about a few things:

The SRT Intake. What gains does it offer? I have heard good things about it, yet I want specifics. Will it improve Gas Mileage, Acceleration, Top end, etc.? Also how is the sound? Too loud, or just right?

Next, a Performance Torque Converter. I know it improves Acceleration, but how does it affect gas mileage?

Also, I was wondering what I could do to make my GS 400 feel a bit "less used", or run like new again. It still runs very well, but I was just looking for maintenance tips, etc.

One final question is how can I reduce the lag with the throttle response? I want to step on the gas and have a more immediate response. Sorry about all the questions guys

1- Srt intake will give the motor more air... little more power and a little better MPG
2-torque converter will not help MPG..
3-If your Gs400 feel a (bit) used is because is a pretty old car.... buy new shocks.. new tires... alignment... bushing etc.. moving suspension parts and it will help the GS feel newer...
4- you can do a couple of things to reduce lag /tranny flush maybe but car comes from factory like that... throttle cable pulley...but it sounds like your trying to make a used car feel like a new car which is hard to do cheap
but rule 1 is to use the SEARCH FEATURE.

Thanks for all the information. I was aware that the Torque Converter would not help Gas Mileage, instead I was wondering how much it would hurt it. I enjoy going from 0-60, and I here a TC is the best way to improve that time, so that is why I was wondering. Sorry I didn't search, I actually lurk around this forum quite a bit and I hadn't seen the information.

for throttle lag, reset your ecu...pull the ECU-B fuse and put it back in

High stall TC usually increases 0-60 times by 1/2 sec and 1/4 times by 3/4 of a second and usually 30-40 more hp to the wheels due to torque multiplication. Usually it doesnt affect mpg too much maybe 1-2mpg less?

Thanks for the input TLcoats I appreciate it. I'm still considering whether or not I want to get the TC though, because since it will have a stall of 2800 RPM's or so, the car will not be nearly as quiet.

Anytime. From what i've heard it doesnt really affect the sound except when your launching. Maybe someone on here who has a high stall TC can chime in cough cough

Have you used search? As far as pulling Ecu and pulling neg batt. terminals. From what I remember its because the Ecu got used to the way you drive. Correct me if I'm wrong....

I didn't know about this i will try this tomorrow to see the difference

Thanks again for all the info guys, I appreciate it.

this has to be done with the battery on or off

where is the ECU-B Fuse???

You can just disconnect the negative battery cable for a half hour or so too. Just be aware that you'll lose your saved radio stations and seat positions. I don't know where that fuse is, but I'm sure it's in the owner's manual if you want to do it that way.
