I have had the cam for a while now and just recently installed the Hooker LT's. They are coated and I have a 3" y pipe w/ no cats. I reset my computer and have a 50 miles o it since then. I have finally done some slight a tapping and MAFT tuning. HOLY **** does this thing scream up top!!! <img src="gr_eek2.gif" border="0"> I am still runnning a bit lean, I need to go even richer with the MAFT. The low end power is about the same as with the stock manifolds due to the 3" y pipe which benefits i the upper rpm range. I richened up 2 clicks on the base and WOT and it feels a lot stronger, so hopefully it will keep getting even stronger as I get the air/fuel correct.


Is it normal for me to be so lean with the cam and headers? My only other mods are a lid, MAF ends, with a basically stock catback. I have the base set at 4 clicks rich, and the WOT 3 clicks rich and my Ltrims are still at 7-9 positive. I haven't done any WOT runs yet but I will tonight. Is it the MAF ends leaning me out that much or is that normal with a cam and headers?

4 clicks rich with positive LTrims seems like a lot for just Headers & a cam. Make sure you don't have any leaks on the intake side. I'd try your stock MAF too and see how much that effects things.

Just as was said. I'd put on the stock Maf ends...you probably will be in the ballpark then.

My L trims are very eratic at idle, more so than they have ever been before. I will check for a vacum leak, that could be the cause. I am going to put my stock MAF ends on but will I lose any performance with it, stock screen and all? I just did a few WOT runs, I had no KR and my o2's were between .935-.945 which is a bit rich so I went down a click on the WOT on my MAFT and will have to run it again. It feels really strong although I am sure that I lost some throttle responmse with the 3" y pipe and no cats, but it more than makes up for it up top.

Another thing I noticed today was that if I load the motor down around 2500 rpms and give it a lot of gas to accellerate, there is a grinding/ vibration type from under the car, could that be the y pipe hitting the floor board?

I just got my car back with a TR224 112 and Hooker LT's, 2.5" ORY and mine is running a bit rich. I have just a Lid, ported TB, and full exhaust. It is around .925 at WOT. Will descreening to MAF help lean it out a little? Im getting 27.5 degrees of timing at WOT. Thanks
