boost lag???

[venomous03svt_1]

hey guys,
i put my stage 4 blower on along with all those goodies in my thread, had it pesonally tuned by RICK @ Amazon tuneing on a dyno.fyi. The problem is, when i shift, i get this lag :shrug: . Its jerks you forward like your brakeing and then slams you back after a pause or "lag", and thats inbetween the shifts. anyone know whats going on or how to fix it?
thanks for looking!:beer:

It may be the boost bypass. It should be turned off in the tune, but you need to check. Next would be the driver mod usually, its not tuned properly yet(drvr mod).

is your clutch worn???
my cobra had that problem when i first bought it, the previous owner rode the clutch till it barely cought. my new clutch shoots me forward when im on the throttle and shifting gears

you need the pprv delete. Search on here and buy from lethal.

Call Rick and let him know. He might be able to tweak the tune to get around it. This is one thing my tuner has had good luck with and I'm really happy with it.

Also a nice powershift will stop all the hesitation in between gears.

Do the pprv delete and it will clear it up, most of it can be worked out in the tune but it's very time consuming. The easiest fix to keep the go fast pedal to the floor while shifting!

Hmm? pprv delete huh? so its not getting enough feul between shifts and the pprv delete will cure it?

my clutch should be fine, not feeling any slip or hearing any noises.

ill also let rick know tonight and see what he says.
