4l60e Upgrade help

[red_spider]

hey guys
im looking at changing the servo's in my transmission (4l60e) and the boost valve for my vx V6.ive done some research and searching and ive found mixed opinions on the corvette and billet servo's and boost valves.transgo do a .500 boost valve and a few others brands do .490 or .470
only mods to the car are the exhaust system and the air intake.it will soon have roller rockers and a plenum/manifold spacer,cai spacer and bigger injectors.
looking for opinions or advice on a good servo and boost valve combo as at this stage due to some circumstances we cant fit a shift kit.

.490 boost valve corvette servo and transgo shiftkit i think the 4l60e kit comes with boost valve cant remember been a while since i fitted the last one no need for billet 2nd/4th servos corvette is more than enough

due to a bunch of stupid circumstances (politics)we cant fit a shift kit,but we can do the rest,so just .490 boost valve and corvette servo?

what sort of politics its not a performance mod

what sort of politics its not a performance mod

long story short.we can do anything deemed "non-perminant" to the car that doesn't affect any of the main components.e.g were not allowed to do cam,shift kits,diff gears,etc.
all bolt on mods are deemed ok.performance or not

dont fit anything to the auto then leave it stock and just get the shift pressure changed in the tune

Not worth putting just the corvette servo and .490 bv in? Technically it isn't "permanent" just drop the oil take off the pan change both and put it all back together.

Can tunes we reverted to stock settings as such?
