i just put new 370 injectors on my 94 dodge, and i put lazer cut injectors. i have a 0 plate and k&N. It feel like i have no top end now. I mean its not like its slow by any means but when i get on it it has alot of black smoke but then after i get into it a little more the smoke slows down. The power doesnt seem to be there with the petal to the floor. What could be the problem?

 

Do you have either the 3K gsk or 4K gsk done yet?

 

i put some washers in were the springs are to kick up the limiter. my brother has the same setup on a 98 12v and his doesnt have this lack of top end power.

 

choking it out maybe...Hows your boost look?

 

i get up to 40 psi at wot

 

Have your timing bumped to 15-16* may help...

 

Are you still running the stock turbo?

 

Sounds to me like you have met the end of your turbos efficency range.Also,remember that just because you add or modify the governor springs does not mean it will make power into outer orbit past the normal efficency range.....Andy

 

stock timing so far need to change that. i also have the stock turbo. do i need more boost or what is the problem. I do know that i cant get any more boost out of mine nor would want to try and also know that i cant go much higher then 50 psi for my head gasket. What is the problem with my turbo if any at all? Thanks

 

Sounds like you need a bigger turbo to get more air. Your stock one is maxed out it sounds like. Look into the HTT or a S300

 

anything over 35psi is just hot air and non efficient with the stock turbo. So I think u need a bigger turbo.

 

thanks well thats going to be awail need to save up. But thanks for the help again!

 

well i changed the fuel filter and lowered the boost down to 35 psi and i got alot more power but now the egt's can hit 15k easy. So will have to keep an eye on that.
