My problem with the TPS is fixed and there are no more codes. However, the engine surges when going WOT. Top of 2nd gear is worst. 4000-5500rpm. Do I just have to wait for the computer to learn the 1:9 ratio rockers? I've been told that its not valve float cause that would stop the revs from building completely. What I am experiencing is a misfire like feeling.

This is a confusing post. I'll just make a vid and have it posted by 11 am central time tomarrow.

what was the fix Prescot?

The vac line was broken in a hidden place. Damn brittle crap. Was only a $20 fix, no biggie at all. If GM used better plastic lines it never woulda happend. Now I gotta figue out why its surging. :? It feels like intermittent lack of fuel.

I see in your sig that you have done the boost bypass mod?

Can you do me a favor and loosen the bolts and try easing up on the plunger a bit?
I have been reading up on 'flash kr' and it seems to stem from high boost cars.Your 3.5" should be safe but I would like you to try. You only need a 10mm socket.
You dont lose any boost but give the fuel system a chance to catch up before going to high boost.

I'll do it first thing tomarrow. Should I let it up all the way or just back up to the stock position? You're prolly right. I never thought of that and can't wait to get a DHP.

Watching this one like a hawk. I'm running VERY high boost for a S1, and currently have my BCA set to midrange.

I think it may be false KR? Take in mind this car is traveling 1100 miles this Wenesday. Again, i'll be poasting a vid tomarrow for all to watch. I'm hoping i'm not over my head with these rockers. :?

With no car its hard for me to 'see' whats going on but after reading up on flash kr and thinking back on my car I wonder if some of my issues were not from the boost valve adjustment?
The status for most is to go back to stock or midway down, the ratio is like 4 out of 5 have issues with a fully tweaked boost valve but you need a good scanner to capture it and it always looks like fuel related.

I'll try to get ahold of Nate (lakevillessei), he has a full range scanner I believe. But I will re-adjust the boost bypass to low and video tape the resaults tomarrow. I am starting to kick myself in the *** for not getting a DHP before hand. I sure hope I can eliminate it.

Dont kick yourself anywhere, we're all here to learn.
Please scan before and after. Look at your RPM, KR, LTFT, STFT, TPS, O2 and MAF.
