SOLVED! engine studder

[exotic_4x4]

first off let me say, with my K&N and throttle body spacer on the dyno i gained 13 hp, for all those non beleivers i have a dyno sheet i can post,(i had my truck dyno tuned) but as far as my truck making the "studder" i put in a cheapy 15$ fram filter cleaned my MAF and truck hasnt skipped a beat, i noticed on my K&N there is seriously alot of room to get fine powder snow through the filter screens, i will not be running this filter in the winter. OH! guys that asked where my filter was mounted, its located behind the LH headlight with the duct work running near the fender and has a tear down around the headlight to suck the "COLD AIR". and as far as my tornado, i noticed a nice increase, i also track my mileage, i average 3-5 more mpg. and also, my plugs and wires are probably 2 months old, i pulled them checked the boots/liners ect. everything still looks new. but problem solved. thats all that matters right?
