i like them only been in for a few hours lol but no they are smoth and they smoke pretty good

 

thanks
and sorry guys gettin you all excited at first i posted it accedentally with just the tool list.

 

Ok few things i noticed in your write up you may want to include as they are a few things we have noticed over the past few installs we have done.
First thing i noticed was you didnt mention what to torque nozzle cone back down to its 55ftlbs.
Next a little white grease and new copper washers put grease on washer slide down onto nozzle will hold it into place when reinstalling into injector bore.
I know they dont say this but the feed tubes and injector connections are supper sensitive and the smallest little mistake and they will leak and they ussually leak good when they do and just get worse and worse. Keep the injector feed tube and injector they came with together and go back together doesnt matter which cylinder like the exhaust rockers do but they seem to match up better if you do it this way.
Also when you go to reinstall the injectors in the bore and put the 8mm hold downs back in and just hand tighten them down and then back them back out to finger tight then slide in the feed tubes and torque them down then back them out dont take out just loosen nut back up this makes sure they are seated together well then torque the hold down bolts to 89inlbs which i dont think you mentioned and then torque the tube nuts to 33ftlbs which you did. But other then that good right up man and the pictures will help people alot.

 

yea i for got a few things im gettin tired didnt think it was goona take that long but yea read this along with my post lol thanks for the imput

 

I can only imagin I have slow speed dial up i couldnt imagine doing that type of write up with my connection speed but good work man.

 

nice write up! it will help me for sure in this coming week I hope. did they really feel like the advertised power of 120hp?

 

How's does the extra 120hp feel?

Are you happy with the mod?
