Alpine tapex not making any power....

[irondave86]

So I went on my first ride of the year. The sled ran perfect the first part of the day. I made a few climbs and the sled was making good power. On the way down from the fourth climb I drove through a snow drift covering the sled with snow, and it never ran the same after. As soon as the boost would come on, the sled would fall on its face. My AFR's looked good, my tps's sensor checked ok. It seemed that when id let the sled cool down it would run ok for a few minutes, then same problem would come back. Also I used almost an entire tank of gas, and for the distance I rode I should have used less than half of a tank of gas. Ive had the sled for 3 years and nBever had a issue with the sled and I'm kinda at a loss where to look next.

Sled: alpine tapex, pure logic box. Standard head shim. 1800 or so miles.

Any help would be much appreciated.

Thanks id86

not a lot of info but i would suspect the logic box. WOrked great and then all the sudden it doesn't. Pure logoc boxes were famous for that. With the info you are giving thatis my best guess. swap it out and check it.. Good luck.. Also Alpine might be able to help. If it is gone you have a perfect opportunityto get a boost it system. Much better IMO..

I agree with Sylvan about the box and boost-it. Also have a powderlites Logic box id sell you cheap if you needed it

you may have poped your intercooler off at the top of your climb when you let off the throttle, you wont notice it till you get back on the the throttle again.it could be the box to but they usually will have interment probs then die.
