Still have a Hard miss in the upper Rpms.... I just put new NGK t-r6 @.032 plugs in and checked all the wires and every thing was good..I have a msd 6al-btm.. it feels like a injector locking up..I doubt it is...but it feels kinda like that..... I have 42lb svo injectors with the stock intank and the in-line pump from ATI... could it be a Maf problem????......I have cleaned it before and that helped some......... I hate the missing...it drives me nuckin futs......

 

anyone wanna help with this............



I change fuel filters today and it got alot better...the old on had 40,000 miles on it..... that tells me that it has to do with the volume of fuel......What do you guys think I should do......should I swap out the old intank for a new 255lph from sumitt and keep the ATI/bosch inline.....or get ride of it?....

 

Swapping out the stock fuel pump for a 255lph pump will help your fuel concerns, if you keep the inline pump, then you will have a set up that is the same as mine, and it is doing just fine at 437 HP at the wheels. The stock pump was not sufficient for me.

Hope this helps
