Lots of people ask of gains with intake and headers AND a dyno tune. Thought I'd post mine.



Car is a stock 2001 coupe with a K&N FIPK and TPIS headers, Random Tech cats and X-pipe.

I don't have a baseline prior to header/intake install as I did the install myself prior to any dyno runs.

The "poor" pull is with old plugs and prior to decarboning. Tuner had me Sea Foam the engine and install new NGK TR6 plugs gapped at .042. "Good" pull is after foam & plugs.

Max power is 327 hp and 342 ft-lb at 12.3 AFR.

Jim at swtuning.com in Oklahoma City did a great job. Spent a lot of time getting it right, including not charging any additional money for the second tuning session a week later after foam and plugs.

Nice... what year is your car? If you drove it harder you wouldn't have to decarb

Yeah, funny but I'm not going to bite..... Car is tracked monthly and driven pretty hard.

Post says it's a 2001.

Sea foam was needed due to oil carry over prior to catch can install. I installed a catch can about 2 months ago and found I was putting 22 ounces of oil to the intake in 4 - 15 minute track sessions at Hallett.

Now it's all going to the catch can. I've completely bypassed the intake from the crankcase ventilation system (i.e., loop).

Wasn't "carboned" from driving slow. Was "oiled" heavily from driving hard.....
