No, just quit chasing it. The car runs good, and at that boost level 6-7 psi im out of fuel withe the single dw400. Im on e85 btw

It doesn’t sound like anything super abnormal, but if your really concerned about it you could always send the unit to vortech so they can check it out

I have a beefcake special on my s197. Love it! And as many will say their customer service is second to none.

It’s a mechanical autometer, also checked it with a second boost gauge.

Good to see this. I’m thinking either gen 2 or 3 short block for my s197 with a Paxton ( beefcake special of course) as soon as the stock block has had enough.

had to get out the laptop. So the torque source is trans truncation. What I am looking at is the throttle angle source, but after looking at it further and realizing that I have torque intervention disabled in the tune I don’t think the throttle angle source is affecting my actual throttle at...

Torque source is torque reduction.

Yes of course

Think I may have figured it out. I was looking over some data logs tonight and I just happened to see that my throttle source was torque reduction. I looked at the throttle angle and sure enough 62%. The throttle closing would definitely explain a loss in boost pressure as I think the slight...

Took the air intake off of the blower and saw 10 psi on the gauge, but now I’m definitely out of fuel pump. My aft is .85 lambda at 6400. But the power felt right on for 10 psi. I’m going to put the wastage back on it and just drive it the way it is for now. It’s plenty quick and a blast to drive

I feel like if the car was truly at 13-14 psi like the air load indicates my dw400 wouldn’t be enough to keep my lambda at .790-.800 on e85

For sure!😂

This is next on my list. I think this test will reveal a lot

I have no doubt the blower is flowing enough air, but the manifold boost is simply not there. It’s 7-8 psi. I could buy one boost gauge maybe being defective, but two I seriously doubt. I don’t think using air load or maf pound per minute is an extremely accurate way for determining boost. For...

I’m not. I don’t think it is because there’s not enough pressure to make it open. I’m wondering if I some how could be belt slip or if the factory air box is choking it out or if there’s a big leak somewhere. It’s driving me nuts but I’m so busy with work that I only get about an hour a week to...

Not according to my gauge or my butt dyno. Also odd that the boost reading, the maf pound per minute and the air load stays the same with our with out the Wastegate

83. 33 , but having come from 850 wheel 19 it’s definitely not making the power indicated by the maf or air load

I missed the boost

Perhaps

In theory it should be given the barometric pressure of 13.9, but it’s not adding up to manifold pressure (boost)
