MeanGrn99GTP I ran a 3.6 setup on a gen v on my 04 with 1.84 yt rr stock springs, sd headers, 104s, and 180° thermostat.

If u would like I have DHP power tuner and I run to the cities alot if u want I can either set up up with my old 3.6 tune or I can run some custom tuning for u

That would be great!

I just bought a stock TB so I will try to swap them today or tomorrow. I got a used M90 and LIM with it too for $125. I am going to port it and rebuild it.

Time to put a stock throttle body back on it or get an actual tune.

160* doesn't matter, proven they actually run 10-15* hotter than the listed temp. My 160* cars always sat around 175*~, which is enough to have the knock sensors report (anything less than 169* I don't think they give a sh1t).

As for the rest of the mods. TB spacer is worthless, throw it out. Iridium plugs? Nope. Chuck them. Get cheapo 104 copper plugs.

Rockers, headers, tune, and a 3.4" should be just fine knock free with at least an 04+ timing table.

not always, i had 4º kr after these exact mods were installed. being i have a tuner i was able to tune it out. 04- 05 timing its to high really. back to stock worked best with maf tuning.

What gasoline are you running? E-10? E-15? Is it brand name, or from the crappy gas station that sells really cheap (but really old) gas?
 


BP 93 octane. 10% ethonol.

I just bought some copper 104s. I will get them in today or tomorrow and video another pull.

I just replaced the o2 and I am getting an o2 slow response code now. I just figured it was the original with 93,000mi it wouldn't hurt to put a new one on. This is a denzo.

What o2 does everyone else run?
 
Is it a 1133 code??? All that is saying is that it once the car reaches closed loop mode that it didn't switch between rich and lean enough times in a given amount of time. I think GM cars is 90 seconds is how long it runs the test, figure it wants to see 60 switches but it saw 55 or 58 more than one time it will set the code. I dealt with it when I did headers and after a few times it stopped popping up.

If so, just clear it. It's a pretty common code anytime you have headers or aftermarket manifolds to the car.
