I haven't played with the timing at all mostly because I couldn't find any good info on how far to change it and what to look for. I also saw a lot of guys that were using Eric's chip right out of the box so I didn't know if I should have played with the timing much. My chip is stamped 23/21 deg...

The ECM was definitely reset. I have tried adjusting my fueling up and down with no real luck. I can increase my spoolup by leaning out but before I can get anywhere even close to where it was I start hitting knock retard. And I double checked the voltage at idle and it goes between 13.8 and 14.2.

I will double check but I believe it hangs around 13.7 to 14.1 last I looked. I will double check it in few minutes and let you know.

They are a cheap aftermarket header for sure (Ebay find that required a complete rework) The spool problem was there before though and doesn't seem to have changed much if at all. I thought it helped a tiny bit but hard to tell.

1 more thing I forgot, Compression test showed 150 psi on all cylinders.

One more thing, when I ordered the Gen2 I also ordered the Extreme G chip. I found it was a little too advanced for me so I went back to the TT chip. I did put some basic tuning info into it based on my TT chip and there was no difference in the spool time.

This is a problem that I have been fighting since last summer. I apologize if this gets a bit long winded but I figure that I may as well set out everything I have found and done right off the bat. I got the car about 18 months ago and I was extremely new to the turbo buicks. Wanted one for...

I had the battery load tested a week or so ago. I was in picking up a battery for my 56 Pickup and had the car so I had them check it just because. Is there any way to find out if the car is in limp mode? It makes total sense. Also could shorting the system out have done that and the chip is...

I took your advice and picked up enough vacuum hose to redo everything under the hood. I found a few that were starting to loosen up a bit so it definitely needs to be done. (Just picked it up today so I have not done it yet). I also thought of something and curious if it could be part of my...

Out of curiosity, with the mods listed what do you guys think that car should be capable of if it is running well?

The wastegate moves freely with the linkage disconnected and you can hear metal on metal contact when you close it but I will definitely have a look at that tomorrow. I didn't notice the vacuum line so I will fix that up tomorrow as well. (good eye, thanks). That is a bad angle pic, that rod...

Thanks a lot for the input so far btw. It is greatly appreciated.

Few pics of what I have to work with.

I have the boost set at around 15 psi right now and a new wastegate actuator on order. It is weird, even building 15 psi it has almost no power compared to what it did. Maybe a dumb question but the O2 reading, is a higher number richer or leaner?

I couldn't see any marks on the linkage to show exactly where it was so I started low and worked my way up to the 22.5 boost range. Now when I walk on it it jumps to 22.5 and then slowly creeps up to around 27. Today I took it out for a ride and I tightened up the waste gate rod a bit just to...

If the rod is turning easily in the diaphram, does that mean that it is likely leaking by? What do you think that might cause? I am seeing a bit of creep up on the boost which I don't remember seeing before. I really have not had a chance to drive the car a whole bunch yet so I couldn't say for...

Well that might explain what is going on, the jam nut came loose and the rod turns inside the diaphram quite easily. From what I saw the jam nut loosened and then it simply vibrated loose. (Extended the linkage). I shortened the length of the rod little by little until I hit the same boost...

If anyone can let me know how I can post a link to some pics of the car and mods that would be great. The chip has a hand written tag, top line says TT 5.6 3755, middle says 60# ALCOHOL, bottom line says 23 deg/21 deg 20-24 psi. Intercooler is an RJC Racing, (bloody huge lol), Turbo is a...

Hi, new here and very new to the turbo buicks. Wanted one since I was 16 and saw my first GN and finally picked one up 22 years later. I do not have a whole lot of back ground on my car other than what the seller told me. According to him: upgraded turbo (didn't know more than that) bigger...
