Word!!! I really like his stealth kit. Fits nicely under the stock or similar spark plug/coil cover.

 

The COP kit is for sure a great kit, BUT if one of your pull need smooth 10 you cannot use it for a comparison.

 

I added the same pulls with smoothing of 1.

 

Great Results, I just installed this same setup (used spoolinup cop) and car feels much smoother. I do feel a hp gain on the butt dyno... I reused my old spark plugs just opened up the gap to .028 from .022 and I have no blowout.

 

can't go wrong with matt's spoolinup cop kit !!!

i purchased a set with new coils, and also the high z injector resistor bypass, great products and awsome work from matt...

-Diddy-

 

When I had the stock coils car felt more rough revving threw the rpms after the cop from the butt dyno I even told matt i gained 10 whp or more best mod for the money.

 

Did you use RPM 2byte? Did you use the same piece of asphalt to do the pulls? Dyno sheets coming from datalog aren't so precise, if you want a barely acceptable result in terms of accuracy you have to be very meticulous.

 

Quick question. So If I just installed a COP tomorrow would my tune need to be re-adjusted?

 

Was it back to back runs? Regardless I've heard nothing but good things about his kits and have full intentions of purchasing a used setup with my tax monies

 

Cough Cough* Group buy/new thread?

 

Im down if someone will tell me if my current tune will have to be adjusted.

 

I would not think so. It should not effect Air/fuel ratio or timing. In my eyes it provides a "cleaner" route for the spark to reach its destination. Then again, I'm not a ecu "tuner."

I agree.. I would venture to say it's the same as changing oil, plugs, new gas etc.. Something that you wouldn't think would effect tune. Plug gap and all would remain the same as well.

 

I want one!

 

How long did it take to install? Been considering doing this and now that I see these results you inspired me.
