Joey told me the performance of a t500 pump is very dependent upon what condition the pump was in before he does his mods. His mods will help a worn out pump work better, but his mods on a strong pump will yield the best performance gain. At least that is what he told me.
That would be correct.
The modifications that are done to the pump allow the pump to work better, but its not a modification like the ADR or the Stealth style pumps.
Your getting a stock modified pump back not a completely modified pump back.
Honestly, These t-500's ramp instantly. I dont' have AE, or I would have provided the info for this in my article when I posted it.
You hit go pedal, and that pump is turning oil, no delays.
But this sorta thing all depends on how your tuner tunes the truck as well, so most things are not a fair comparison. even against the ADR, due to having to tune a bit diff for the way the ADR works from what Jody has told me.
