Problem when WOT

[GCeclipsegst]

ON way home today pulling out of a gas station I went WOT in first gear. All was smooth to around 15 Boost. It felt like I hit the breaks real hard and car slowed drastically. I tried it again and same thing. After boosting to 15 the car looses all power. The car pulls great up until max boost.

is the car backfiring at all?

This might sound a bit crazy but check to make sure that your battery bracket is tightened down. I had this problem once and what was happening was the battery was sliding backwards when I hit boost and the bracket that goes over top of the battery was hitting the positive terminal and sparking on it. Then once it cut out and bucked really hard the battery would slide back forward again and car would keep going. Sometimes its as simple as that

no backfiring at all, and the car has no battery bracket at all.

I would honestly say that it's just fuel cut. Either I'm stupid and can't find your mod list, or it isn't there. 15psi sounds like fuel cut on a 14b with 450's though.

I'm backing up Mecheng1993,,,,,,, Can be just a fuel cut.

Add your mods to your profile so we know what you have, with out knowing your mods, there is no way we can give you a more accurate answer.

Boost gauge 1g bov and mbc all else is stock. Isnt my turbo a t25?

Do a boost leak first and go over 15psi, Check and fix all leaks, if there is a leak, don't just ignore it because is small, fix it and report back the results.

Why would you run the car without a battery bracket? The battery probably shorts out on the hood, or is damaged internally and shorting out.
