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

 

I'd still be in.

 

let me know if anyone backs out also

 

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.

 

I just ordered mine.....

thanks for the heads up though..I guess I will put it on my 01 5.3 yukon....

 

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.
