I have an 05 LLY and i just bought a set of EDM 40% injector tips for her off ebay and didnt come with instructions. How hard is it to first get to the injectors then taking them out and swapping the tips??? Also has anyone else purchased these or a similar product, what was the effect on power, mileage, EGTs, etc.?

i have changed injectors in a parking lot.took me about 20 min per injector.

If you can't figure it out on your own, I am sure Eric at Merchant's can give you some direction. Although he's going to be really busy for the next week or so, well he's always busy, but if and when he's got the time, Im sure he'll lend you some advice.

i have changed injectors in a parking lot.took me about 20 min per injector. seriously?? thats impressive....was that an lly motor??? i have heard it is not so easy on the lb7

lly very easy to change injectors, the lb7 will take twice as long , the injectors are internal versus the lly be external

the injectors themselves are very easy to change, the tips on the other hand are just held together by a nut on the injector. probably easy but never tried. i don't know the torque though.

Thanx for the info... just need to find some time to start wrenchin!

Honestly it will take you a day to get to them all, unless you've done it before. Some you can do in 20 minutes, and some take an hour removing stuff to get to them.;)

if you haven't done them befor i would make it a weekend project. but the LLy isn't hard to do.
