4.2L Headers

[palitoiii]

Thats pretty good #'s. Marshall how was the check engine? With just the headers did it have the check engine light on? And if it did with your tune does it fix that? I dont want to have inpection problems here in NY.

novajoe, you probably have mentioned what you have done before, but could you recap any and all mods you have on the truck as it sits now? It would be nice to reference what you have on the truck in a post close to the dyno chart so people don't spend much time looking for the info.

Thanks!

And again, well done Kooks!

Is the smoothing value the same for all three runs?

[novajoe]

I would like to thank everyone who has helped out with this project. This would include the staff at Kooks and PCM of NC. I got the truck back from Kooks Tuesday night and you could tell right away that the motor was breathing better. If you floored it it came to life and had no hesitation, and the sound real didn't change that much (a little deeper). The first day it took a little bit for the computer to learn the headers but after 100 miles it was getting happy. Then this morning I dropped it off at PCM of NC and they worked their magic. The numbers are great but the seat of the pants meter put a smile on my face. I now have just over 250 miles on the new headers and even with being aggressive and having some fun (higher than normal rear tread wear) I still average 16.9 MPG. I expect it to be much higher once I return to normal driving and repeat a couple month average. I will say that this system is worth the investment. You will never have a cracked manifold, better looks and performance too. I anyone in the Charlotte area want to see it in person please let me know.

I will also be adding the E-fan setup from PCM of NC in the near future ( I got a look at it today and I think it would be a shame not to add it to the mods on the TB)

After the tune there is no light and I asked about inspections as we have testing here in NC and i was told that after the relearn it will pass.

The mods list is very simple. NONE! This trail blazer was bone stock. This was the first mod. This is my wifes daily driver, but I can tell you after she drove it with the headers she now has the mod bug. I now have a to do list for her truck! LOL

As far as I know. Can you even select different smoothing for separate dyno runs??

So is the system your selling going to replace my original Catalytic converter also? or do I still need a new catalytic converter since I believe mine is plugged.

I called and was quoted a price of $700 and guarenteed 20+ hp gain without retune. Will the price remain the same with only a 10 HP gain without retune.

Dude go look at the pictures, your answer is there..

Why would you think the price of the part would change with HP change? The tune is completely separate from the exhaust changes.. The cost to make it does not change ..

[XUVFISCH]

Thanks, But I was hoping Drew would answer my questions since he is selling it.... also would it be the same fit for the XUV model?

I noted the tune lowered TQ with headers. Could this be changed to maintain the lower TQ?
