Odd RB20 issue

[bades]

Ok guys well the other weekend i took my car to the strip and did a few runs.... on my 2nd run I launched and the car bogged really bad.... then it got up and went... well afterwards my vacuum dropped to 13-14 inches whereas it has always been around 16-17 inches..... and ever since the car has felt awefully laggy.... as in i felt like i was driving a car wit a 35r on it at around 4grand the car opens up and pulls hard like before.

any ideas???

Im gonna check my timing this weekend and look to see if my belt jumped a tooth.... i checked the ecu and i have no fault codes... just curious as to where this came from randomly....ooo and yes ive searched for boost leaks.. ive cum up with nothing.... so there are no leaks....

shoot sum opinions!!!!

good news though... i ran a 12.7 @110 wit a 2.0 60ft.... lol

Boost leak. Sounds JUST like my car when I have a leak.
