ok so today I found out that I'm not mechanically inclined but that's not the point.

I installed an MSD SCI ignition along with a used 1987 leading coilpack (mine has an erratic spark), following FC3SPro & a couple other write-ups (Josh_Fucking_Blair )

I test drive my car & it feels VERY DIFFERENT.

I can HEAR the boost hit ~3000rpm but I can't FEEL IT. (heard from both the engine & exhaust)
Full throttle was tested in 1st & 2nd gears.
One would think that my powercurve has smoothed out...but THAT SMOOTH!??!?
JUST FROM AN MSD & BETTER COILPACK!??! (assuming the coilpack is in better shape)

This is how it feels like after MSD & Coilpack:
Like I don't have a turbo but a very powerful N/A with whining noises.
My car also doesn't dip like it used to when I floored it (rear goes down when boost hits thingy)

Before:
Like a turbocharged car where you can feel the boost kick in @ ~3000rpm with the rear dipping



I'm actually quite worried because I don't know if it's the MSD or the coilpack.
Would the Series4 coilpack I'm using now be set to produce S4 power levels????

Here is a picture of my erratic coilpack dyno from a mustang dyno:
(red is RPM, pink is power. Bone Stock S5TII)

 

anyone??

 

check your ignition timing..... sounds you have it way retarded or way advanced

 

haha im of no help but i love the way that ******* back in drops.

 

Check to make sure it's still sparking.

Pull the spark plug boots off the spark plug ends and put them close to the strut tower bolts/studs (after taking the rubber cover off).&nbsp Crank the car - do you hear/see sparks?
