boost leak prolly, what plugs? stock boost? tuning on a stock car shouldnt be the problem. I never EVER heard of a car breaking up because of it having a fmic and exh oh and a pump.
whats ur plugs gap? prolly wont be codes.

im willing to bet hes not running stock boost...
if it was a boost leak he would be most likely experiencing those issues in other gears also not just 3rd IMO |

Gap the plugs down to .028-.030. If your not sure how much boost your running, your running straight off the stock wastegate right? That should be roughly 7 psi. If your running stock boost, stock injectors, the tune shouldnt matter much. You said your running NGK plugs, whats the heat range on them, better yet, just tell us what it is exactly.

Get rid of those super stupid expensive iridiums now and go get some 10$ a set plugs (bkr6es or bkr7es)
.28-.30 for the gap always - and see if it still does it. If so - do a boost leak test (unlike what sleepy says - it can show the effects of the leak only in higher gears where theres more load/volume of air - theres significantly less airflow in 1st/2nd gears than in 3rd and up - and the maps on a stock sr get way richer up there than in the earlier (lower load) parts of the map)
