Boost leak test, and what mods you have?

Also check the cas and maf.

what plugs and plug wires you running?

 

[s1gtsi]

new set of stock plugs new set of stock wires and no mods the exhaust is not on the car but been that way before it started doing this it only breaks up when you smash it build boost around 4200 and up its like a fuel cut but still builds power

 

[silver bullit]

Well check the maf and cas wires, clips and the units them selves and then do a boost leak test.

You have a 14b which makes max boost at 3k not 4k. Unless you have a different turbo.

ok well 3k sorry but im just trying to figure out the break up so my buddy has a boost leak test so i'll try that tomorrow

 

[93_tsi_fwd]

what kind of plug /plug wire do you have? (ngk, chanpion, magnacore, etc. etc.) I had that problem on my 1g cause of the plugs was not gapped properly.

 

[s1gtsi]

there ngk i beleieve not sure i'll check tomorrow

ngk bpr6es gapped to .28 are what you need.

you can go with 7's if you make more boost, the 6's are good till about 17.

 

[s1gtsi]

im running 14

 

[93_tsi_fwd]

Then the ngk bpr6es's are perfect for your set up.

 

[s1gtsi]

someone told me to set my timing at neg 5 so when it builds boost its at 0?

 

[BigSorn]

Then the ngk bpr6es's are perfect for your set up.

agreed!

14 on your stock gauge or aftermarket?

 

[kqodprez]

I know that it will also do something of that nature if the coil pack is going bad, or if the stock fpr is being overrun. Where did you get the ecu from? Might be in the box still.

 

[s1gtsi]

i bought it off someone on ebay who rebuilds them

 

[s1gtsi]

14 on stock gauge not best gauge to go by since it reads off of fuel and air ration from the computer
