i dont know if youd call it lazy. its hiting 1.6 60's while spinning the tires. the lazy launches were on the wrong 2 step so it saw little to no boost. i was able to get to 6psi on the 2 step yesterday just playing around with it infront of my house.
and that dyno "pull", the motor spiked 10psi for an instant and then settle at 8psi. i wanted to get some solid 10psi pulls but i didnt even get one full pull. ill have to play with the boost controller more to get it to even out

most of my launches were slow due to the pms's 2 step pulling fuel which limited my ability to make boost on the line. when i realized you need fuel to spin the turbos i went to an msd 2 step which allowed for more boost while on the trans brake. went to the track once like that and just kept spinning the tires. then i realized, if more fuel makes more boost/power, a lot more fuel will make a lot more boost/power. so since the last time i went to the track i went into the wot table of the pms and gave it more fuel below 3000rpm as well as almost 40* total timing. it was the change in the wot table that made the motor hit boost fast and hard on the dyno. it has yet to go to the track since that change was made
dont know how much boost ill run. ill probably pull the plug when im comfortably over the 600rwhp mark. 625rwhp sounds like a nice round number to me

800 to the tires is really pushing the limit of my aod and well beyond the capacity of my fuel injectors and fuel pump. if the motor was n/a the a1000 could probably support 800rwhp but boosted itll never make it. i think they are only rated for 800block hp on a power adder motor. ive already got about $1500 in my fuel system i just cant afford any more. that includes a sumped tank, a1000 fuel pump, 2 aeromotive fuel filters, aeromotive fuel regulator, -8 braided line from tank to fuel rails, -6 braided line from fuel rails back to tank, 55# injectors and more AN fittings then id like to add up.
