nope i got you beat like 2 years ago maybe 7 min at idle.

buy buy pistons head and valves. the timing belt was sill good though. lol they tried again and it made it to the dyno and that was about it.

needless to say i found a new shop and havent talked to them since.
anyway, keep going it will be worth it. i hope it gets beter for you. we need as many fast subys as possible there to many people that dont believe. lol gl
