That stock MAF is going to choke the hell out of the aftermarket TBs. I'd try and borrow a pro-m 80 as well. You will see a bigger spread and more gains.
good point mackey, will consider getting a new MAF if i get some Tbodys to test
if nobody lends me tbodys to test im not wasting a trip to the dyno (100$)
I emailed someone at BBK and offered to put a deposit to borrow some throttlebodies but they are out of stock on 65 and 70 mm throttle bodies, he said they might make some more in 2 months.
