gutless on take off

[b.garrett]

Help me with my problem please! My GN has no power on take off and I live in texas with no buick specialists in sight. See if you guys can tell me what Im doing wrong... 84 car with cold air retro fit stock 84 bottom end with all arp fasteners.Stock 87 intake and heads (gasket matched porting) harland sharp roller valve train ,comp roller cam. Arp studs, stock ported plenum,stock throttle body. 55lbs injectors,3"mass airflow sensor w/translator all 3"piping big K&N filter Walbro pump,hot wire kit.Big intercooler(600hp capable)3"piping.Stock headers 3"down pipe,applied tech waste gate not sure turbo size I think it was t-60.
3"exhaust dual flow masters,no cat! Pro built 2004r 3500 precision stall,mosier axles. Turbo tweak 93 chip,taylor wires, a/c stock plugs. Now...car easily pulls 21lbs. boost(race gas 23lbs.),put out only 350 to rear wheels on dyno,runs 12.99 quarter mile and will barely power brake rear tires! I have no experience with turbo buicks but I always loved and wanted one so I saved this one from a collapsed barn and did this all myself with almost no help.Almost every part came from Bruce@Aggressive. Please help me help my dream car reach its full potential! thank you.

something is wrong..do you have a scanmaster? post up your rdgs
do you have a matching chip to your setup?

 

[b.garrett]

I have scan master no idea how to read it Bruce says all readings are normal.please tell me what you would like for me to get and i will go drive it tomorrow and try to answer as best as i can. Chip was matched by Bruce but I wondered that too what do you need and I will look for that also. And thanks for your help

 

[87chrisss]

most of the time you would call eric @ turbo tweak and he'll match the chip for your setup.. take a drive tomorrow and scroll thru your scanmaster and log everything you see and post it on here and im sure we can help

Where in Texas do you live?

How much boost r u building when power braking... Is your check engine light on?

 

[b.garrett]

OK I appologize for taking so long to post this I have been very busy.This is the follow up to my previous post for help.Please let me know what you guys think about these readings...by the way when I got my scan master the box was in bad shape and there were no instructions or any thing,I just knew how to plug it in from previous experience clearing codes on other GM cars.
idle wot
O2 718/750 800/832 ? there are no codes or check engine lights.

yes the question marks mean I dont know what these values are supposed to be or even what some of them mean.

Sorry I forgot to say I live in east texas near Longview. and I cant get it to spool over 4 ish psi.when I power brake.

 

[Fatpig]

I had a very similar issue with mine.it ended up being the o2 throwing a code and putting car into limp mode. Could only build 2# at line. What convertor r u running and what rpm is that 4 psi @

 

[Fatpig]

Oops I see convertor. 3500. What rpm r u making it too.

 

[b.garrett]

Im not sure and now its raining cats and dogs.

...................................3"down pipe,applied tech waste gate.................... Pro built 2004r 3500 precision stall.................

The 2 items I would first check would be to see if the waste gate is working properly, especially seating when closed, and after that check the converter?

If the waste gate puck or valve is leaking, or not seating properly, you will not build to the boost level you need.

When you verify the puck action is proper, you can then check if the converter is actually the stall as stated.

There is a ton of info on the vortex-buick website to learn the basics of your turbo regal. Here is a link that will help yoybto understand your scan master numbers:
