strange problem cant figure out

[danielkile]

Alrighty well my problem started when my timing belt tensioner broke and i had to fix it. I am using the dsm link 2.5 so when the batt. is unplugged you lose your tune but I saved it on my computer the problem is now that whenever I get any amount of boost my air/fuel pegs to 10 and my car just backfires like crazy and wont speed up. The car ran fine on the tune before and I dont think i broke anything because it runs fine until I get into boost.

Does the car run fine at idle? Did your timing slip when you noticed your tensioner was bad? Have you done a boost leak test?
