Having problems with my truck

turner97 · Mar 6, 2015

So like the subject says having issues.its a 97 auto I have 350/200s,terminator twin hpops, e fuel set at 80 at idle t-4 with a s472, 140v idm hydra with Gearhead tunes comp 910 valve springs not shimmed new map sensor and boost fooler set at 20 right before map sensor. And for some reason I'm only getting max 28 psi on street and dyno it just doesn't seem to have the get up and go . I dumped it saturday and it showed 401/572 any ideas what it could be

Are your tunes for your setup if so why the boost fooler?

turner97 · Mar 6, 2015

Yes they are besides bigger turbo now instead of my 64 mm 2.5 charger but it still didn't seem right with that charger and just figured I'd have it to truck the map wasn't sure if 97 needed them cause I knew when buildng my dads 01 it kept messing with it

why 80 psi on the fuel?? 65 should be plenty.....

I was having problems with it dropping under wide-open throttle and I found out that it was my pump and I just haven't changed it yet

Have you pressurized the induction system to check for leaks?

Do you have any soot marks on the up-pipes, exhaust manifolds, or turbo turbine housing indicating a drive pressure leak?

Boost leaks. ^

Is it black smoking real bad?

Do you have a video of it on the dyno?

I agree with the boost leaks.

Get rid of the boost fooler, lower the fuel pressure.

I saw you have e-fuel, but do you have a regulated return, and what size are your lines. You need a lot of fuel to supply those injectors.

Yes it has a regulater and it has good size line and I built caps and pressurize the ic and pipes no boost leak

You got to pressurize the whole system. Not just the intercooler.
All you need to do is pressurize the inlet at turbo. Regulate it at 30 psi and check for leaks.
If that checks out it could be a exaust leak before turbo.
