[turner97]

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

Does your fuel pressure need to be that high? I've always read where 65 psi should be good and sometimes higher hurts more than it helps. I could be out to lunch too! Cheers!

Does it smoke a lot? If you had aggressive fueling and that low of boost, it should smoke like a freight train.

If it's not smoking like a freight train, I would say the fuel isn't there. Are you sure you're tunes are setup appropriately?

Sorry I have it set at 65 now and yes she smokes like a train

Like we have said in your other thread asking same ?

You have a big boost leak. Or huge exuast leak not driving the turbo efficiently. Your down about 10-14 psi in boost.
This is why it's smokes and is lazy to spool.

Pressurize the whole system not just the intercooler

Yea I'm ganna try that but just figured I would put one here to just incase someone who knows gets on this one and not the other

Yes, you need more air. Big boost leak for sure.
