Intermittent Mid-range stutter (ProCharger Stage 1)

[bew]

Just finished up my ProCharger HO Stage 1 kit and took it for a drive.

Like a couple of other guys here, I'm seeing that mid-range stutter at around 3k - 5k RPMs. After 5k she just wakes up and goes, however low/midrange seems to be missing.

I saw a few guys fix this via plugs - however I already did plugs with my install. NGK 6510s gapped to .035. Should I have gapped them less?

Also, could a less-than-ideal-turn in the tubing cause this behavior? The rubber elbow from the blower unit to the IC, I trimmed it quite a bit and squeezed it in, however I'm still not happy with that bend. If it's too much, can that cause what I'm describing above?

I'll keep poking around at it, and probably give ProCharger a call tomorrow morning and see what they say. Eventually I'll have it custom tuned, however I was hoping to enjoy the out-of-the-box setup for a while first!

Pretty sure the kit should fit perfect without trimming anything in the tubing. I'd be concerned if it didn't.

The Stage 1 kit requires you to do some trimming (not sure about the other kits.) It's in the manual (page 18) to trim that rubber elbow until it all fits nicely to the IC. And you do end up cutting a few inches off of both ends. Thankfully that's the only piping tube you have to trim, as it was a PITA with my dull ass clippers.

Just took it for some more driving. Flipping into Sport Mode certainly hides the stutter a little bit, however you can tell it's still there. Maybe I should just try and keep my RPMs at 4500+ all of the time

Interesting. Welp, I stand corrected. Everything in the kit is so organized, this just sounded wrong to me. I'm not very good with a wrench, much better with a keyboard lol. Guess this affirms why I'm letting someone else install.

we always gap at .28-.30, but tune could need some fine tweaking

I think that you have the "tune" problem, maybe this week we are going to have the new tune. :shrug: My car has the same "symptoms" .

Thanks for these, post #184 is extremely encouraging that we're going to get a fix soon. Also it's good to know we're not necessarily "hurting" anything by driving the car in its current condition.

Revised tune will make a huge difference when it gets released. New platform = new problems. ProCharger will make it right, they always do.

Just have to wait patiently with the rest of us, hope here shortly, your having the same Diablo tune problem it seems... To your other comment there was a ton of cutting that was necessary to get that elbow onto the bell housing on the supercharger.. alot more then i expected, said to trim to fit right, so think this is a normal process.

Send us an email to [email protected] with your serial number, and we will put you on the "tune update" list to be sent out.

As for the tubing, we don't trim rubber or silicon anymore, so people can trim it to their liking.
When we trimmed it, people complained it was to short, so not trimming it was a better option.
(easier to remove, then to add)

Yea you guys added me to the list a couple of days ago. Anxiously awaiting the new tune!!

As for the elbow, how important is it for that bend to be perfect? My bend from the head unit to the IC is smooth and not-kinked, just seems tight... maybe I'm just being paranoid.

Your fine, no need for it to be perfect.
The tubing is pretty oversized for what it needs to do anyways.
