Requests 20+ but Actual is only 17-18.

Car runs great but I'm not sure whats up with the mis-match. Took out the Hyperboost BPV's and replaced the N75 this evening and also pressure tested.

There are no boost leaks.

What to do now? Thanks!

Default Talk to EPL

also, would be nice to see wgdc.

not sure why you are having problems using my app.

unzip it to a folder in "program files" and run the .exe

Yeah, duty cycle limited from the looks of it. Otherwise, boost would respond to the deviation.

Default Lol...!

If it was tuned in signifcantly cooler weather, it is *totally* possible. When you're already riding the max, the IAT related DC correction can't do it's thing to compensate.

Default I'm also thinking swapping N75s around might cause quite a bit of variance as well

no n75 i've had has acted the same

Looks limited to me. It doesn't spool hard like a non-limited setup should.

Default The boost comes on a bit late and smoother not to put too much torque load on TIP tranny it was..

tuned that way
