Next Mod?

Just installed new exhaust from downpipe back. Sounds great, but don't really notice too much more power than stock. Looking for a little more power in 2nd gear towing my travel trailer up hills. If I don't get a run at a hill it seems to bog down between 35-45 mph. Other than that it's fine. I am looking to the next mod that will give me more power for not that much $.

It seems like some of the guys said the 140 resistor mod is good one to do in the first round. I guess it helps deliver some extra fuel to go along with the improved airflow. Should be cheap and easy.

He's talking about the IDM Resistor mod.

Not something to try if you don't know how to solder.

I'd have the IDM mod done if I got the right resistor.

The IDM mod is a good one. Thanks for using my link there George. Makes me feel all warm and fuzzy inside knowing other people like my write-up.

The 10k mod isn't that good IMO. Saving up for gauges and a good chip is better.

Also, do you have a larger transmission cooler already? Definately a must have item for towing and even every day driving.

i had your write up on the computer on my bench when i did mine. i had a 110v idm, but it was just as helpful. what kind of resistors did you use?

I got mine from a different member on here who had extras. Not sure where he got them from.
I know that there are different size (physically) resistors with the same specs though. Mine was quite large, other guys have smaller ones. I don't care as long as it works!

Did you upgrade the downpipe with your exhaust or is it still stock? Stock downpipe is very restrictive.

FPR shim is good also. Make sure you are getting good fuel pressure, but not too much. You don't want more than 80psi at idle, but should have more than 45psi.
Between 65-75 is ideal.

Sorry, I guess I could have been more specific. Yeah I meant the 140v IDM resistor mod.
