Me too... I'm HUGE on part throttle and MPG mods.

Tom, you should have made a stipulation for these guys to require before/after dyno tests

They do not work in electronic tb vehicles. At least not in mine. It gave me a reduced engine power message every time I gave it gas. I reset the battery twice.

They are designed for the cable tb's, on the electronic ones they completely cover a hole for some sensor and only partially cover them on the cable ones.

Thusly, they -do not- work in 03/04 trucks, unless someone can prove me wrong.

Tom, have you used any of these? i know a lot of people on here tried them out and basically said it wasn't worth it. If i could see any gain I wouldn't mind paying full price for it. I guess we are about to get a decent amount of feedback from these guys so i am sure my answers will come shortly.

oh if you ever decided to give some headers or converters away, can you PM me about it first so i can get ahead of everyone else.

How about me? I am the biggest non believer of all. I will even provide dyno results.

I'm fixing to order mine up tonight. I'll share, no sense in getting a free one and not sharing.

LOL - I was just about to order one. TByrne, can you cut the rest of us a discount deal? I'm ready to order and try it out. Thanks.
