3.1" pulley and intake

[NH_Redline_Pilot]

Just installed my sfph 3.1" modular pulley and k&n typhoon intake. For about 15 miles the CEL was on, then it turned off. Car feels much faster, boost comes much faster and it sounds great. Only problem is that occasionally in the upper rpm range it will stutter (almost like skip, or maybe some belt slippage??). Anyone else with this set-up incur any of these problems?? Thanks a bunch guys, oh and the friggin thing couldn't pull an old woman of a toilet, i mean like no traction in first or second. Caught rubber going into third too.

Questions...
1) Did you unplug the battery before you did the intake? If not, it tend to throw a code. I would just do it for a few hours anyways.

2) Are you due for an oil change? Mine can sometimes stutter in the 5k range if i am due. It might be timing retard.

3) If not (yes to number 2), then consider getting the NGK 7 plugs from SFPH

4) The dunlops are really hard when they are cold. I get tons of wheel slip on really cold mornings until they warm up.

Those plugs are much cheaper through www.sparkplugs.com (also, talk about a killer site for plug searching )

But I found the BKR7E plugs at my local Napa store.....might wanna call if you have one.
