How much boost should I make? Boost leak?

[slcpunk74]

I have an early 99 with a ts6 pos chip, diy intake, and a dynomax race muffler. No matter if I have the chip on 50,75,100,140 I can't seam to get more then maybe 22lbs of boost and when cruising around town or on the freeway I only see around 3-5psi... I installed my glowshift boost gauge last weekend with a t fitting on the map line. I also did an overboost deal from dfuser. I installed the dfuser between the map and my boost t fitting on the map line. Is this correct?
If it is most likely that I have a boost leak where/how should I start looking?
Thanks guys

That's about where the waste-gate starts opening up. Try unplugging the red line temporary to see if you get more boost.

[slcpunk74]

forgot to add the red line was disconnected already. Is it not kosher to drive like this?

Bump. What should my cruising boost be? I doubt I get more then 5 psi on the freeway unless I speed up to pass or hit a hill.

If you do have a boost leak its a small one. I can hit 30 psi on the 100hp setting, cruising on flat ground at 70 is usually between 1-4 psi. I would try just tightening all the clamps and see if that helps.

Well if that's what your getting then maybe I don't have a boost leak and the lower max boost could just be that I have an early 99..? I don't know if the early 99 made less boost or not, I would guess yes with the smaller turbo housing.

I was thinking that might be it because my buddies e99 only makes 23 but he doesnt have a boost fooler

I got on it last night and I only saw 20psi max no matter what setting I was on... Guess I better check those clamps.

theres a lot of guys, including me, that didnt get an accurate reading by tying into the MAP line. I did that to start with and only saw 8-10 lbs. so I drilled and tapped it into my y-pipe and am seeing around 35.

need to drill and tap your y pipe for an accurate reading. also many members are sceptical of glowshift gauges.
