Yes and yes to your last question.

I'd get a good dual spring, your heads, and re-tune and you will make 400+ at the wheels I guarantee it and that's being very leniant.

Holy ****, I made 640 thru a T56 on a Dynojet. I don't think I'd want to know what I make now on a MD thru the 4k stalled 4L80e! I am just happy I can turn a 10.0x any day of the week and a 9.9x on a good day.

I don't have a lot of input here cause I'm not sure what your problem is but for what its worth i was running 8.7 at 87 in the 1/8th stock.

You need to watch a few different things. 1st make sure your tune is in order, dial in your ve table, maf table, wot a/f and timing ect. Then watch your IAT temps, if they are too high the car will pull timing and lose power. Also watch for knock retard which will pull timing due to the car detecting knock. If you eliminate these scenarios you more than likely have valve control issues due to worn or inproper valvespring setup.

I think I saw you running 9s in the 1/8 a few weeks ago.

You have a bare wire on the sensor that is responsible for making changes to the fuel tables and a kinked fuel line and are asking if that could make a difference?

Got around to replacing my fuel line finally. Check out this fuel line. There were 3 total kinks. I guess I was in too much of a hurry when I was taking my fuel rail off last month. After I get a 12bolt in, I'm going to take it to the dyno to see if this fixes my 5500+ RPM problem.

This is only 2 out of 3 of the kinks


Getting replaced with this (actually slightly shorter, it's been trimmed since photo)


But the O2's shouldnt matter at WOT right?

The O2 sensors are used to make changes to the Long and Short Term Fuel Trim which adjusts the Volumetric Efficiency Table. The PE Enrichment Table(that is used at wide open throttle) uses the VE table as a base and adds fuel at whatever percentage it is tuned to add. If the VE table is out of whack due to bad oxygen sensors causing poor fuel trimming then all of your fueling is inaccurate.

Right. I'm no tuner, so I'll take your word for it

I'm still going to replace the O2s and extensions soon anyway, they are factory O2s. I'll get a retune this year after some heads and possibly a bigger cam

HaHa. So I take it that a simple yes would have better answered the question for you?
