what do u think

About 270 HP at the wheels.

I would agree with around 270. Also, you might not want the Mac timing adjuster if your geting the Xcal tuner. I'm pretty sure you can adjust the timing with your tuner.

Another vote for about 270. But you should get it dyno'd. Lose ALL that C&L CRAP and the cheesy timing adjuster.

What's wrong with the Timing Adjuster?.. Just wondering

The computer controls timing. Those timing adjusters are not the best way to manipulate timing on the mod motor IMHO. The best way is with a handheld engine programmer such as the Diablo Predator. I am pretty conservative about mods though. I am sure someone will disagree with me...

Put it on, dyno it, and then you'll know for sure.

The typical hp increase for a full-length exhuast setup is between 20-30rwhp, depending upon application. Since you have a five speed, you'll see more rwhp than a automatic with any part, naturally. I'm going to be conservative and spot you only 20rwhp for the exhuast parts.

The typical increase in power for a 75mm throttle body and matching plenum combo is 6-8rwhp.

The typical power for a K&N air filter is only 2-4rwhp. The intake pipe will probably yield another couple rwhp.

As for the C&L MAF meter, you might want to save your money and send it back, or cancel the order on it. The stock MAF meter is plenty big enough, not to mention for a new MAF meter, you must get it calibrated to match your injectors. I'm not sure if you can do this with the SCT tuning package or not. If you keep it, you may see a few rwhp with it, but not sure.

As for the timing adjuster, send it back or cancel the order on it as well. Ignition timing can be advanced and adjusted with the SCT package. The typical power gain for ignition timing adjustment is 7-12rwhp. Depending upon application.

I think he is saying that he just bought that car with all that stuff already on it...
