Yes, the tuning was done reading the boost where the MAP sensor connects. My boost gauge is reading it at the brake booster.
Pat did not get to choose most of the equipment on this install. Two other shops had screwed up my engine rebuild and EFI conversion before. He had to make due with what I had in many cases. He did a wonderful job. He did choose the turbo, injectors, muffler, and JE pistons. So the intercooler and location of the air filter were not his fault.

Thanks. I'll try to keep updating as I get the AFR's fine tuned.

Truly professional work.
I'd like to know how you were able to mate the throttle body to your intercooler. It looks like you turned the Carrera intake 180 degrees which explains the throttle linkage being on the right. Even so, the angle would have been about 10-15 degrees off based on my crude measurements. Did you cut, rotate, and then reweld the intake or did you use some kind of adapter?

What is also cool, is that you retained the Kokeln with the Carrera Intake.
Daddy likey! Yasin

I already had the Kokeln and did not see a reason to buy another IC. They did have to cut the TB and Intake and rotate them around to get them to fit. The end result is IC mounts and TB that are "in theory" in stock 930 locations.
I am starting to regret the twin plug. So far it has just added more wires to come loose and leave the car running like crap until found and addressed. That has happened twice now (once before the rebuild and once after). There is debate over the value of twin plug for turbo cars. There is no debate about the higher cost and rate of failure in twice as many components.

Which wires are coming loose? I went twin plug because it was my understanding that when you get to 98mm bores even with lower compression (ie no dome to block the spark travel) the flame has to travel too far.

Got the plug wire replaced and back up to full speed. I'll swap out the plug wires soon for another set that will hopefully stay attached better.

They are Clewett wires. I really like Richard Clewett. He has been great to work with on this system. I don't know if this problem is due to the wires themselves or the 2 different shops that have been messing with them.

I've got Clewett's too. I returned the first set (bought over a year ago) because the spark plug end pulled off several wires when I removed them. Richard sent new ones a couple months ago and they seem to fit great. How old are yours?

Drv2FST: I dont remember which site it was, but theres a company that make hold downs that hold the wire in place so the end cannot pull from the cover without unbolting the hold down first. If you want I could try to find it

I just ordered those from Clewett. I have not installed them yet.

This site has the hold downs and they are pricey at $12 each, but will solve any problems with the plug ends falling out.

I am pretty sure you can buy the hold downs on ebay
search porsche 934 or 935

Clewett has a set of 6 for $58.50. Our host sells the 964 solution "964-602-559-00-M100" for $0.50 each. I don't know if they would work for the 930 but maybe someone does.

Oh I didn't know, I only seen these and thought they would be a good solution, if you could get them cheaper that would be good. After all they are only bent pieces of sheet metal with rubber in-cased ends on them- how much could you charge for that?
I just don't have the problem as I unfortunately don't have twin plug yet
