Dying at 5400rpm,bigger injectiors?

[Grange 185]

When you give it heaps and its get to 5400rpm it splurtters and then changes gear 2nd then dies for a second then pick back up and off we go again. Im not really to much of a mechanic but it feals like its running out of fuel?? Ill do a quick list the mods ive done so far..
Mild cam(168/260)crane. It was in the car when i bought it
Crane adjustable roller rockers,crome molly push rods
70mm throttle body
Custom Tune
CAI,hi flow filter
Twin au thermos

Would a bigger fuel pump and injectors be the go??Ive really got no idea its going to the auto transmission joint this week do get its gears the might have an idea..

Sound like it's hitting the limiter to me, is that the tune I just sent?, the limiter is set to 5650 and the shift points are standard so I would have though that's enough to shift before then?. Try it in both normal and performance mode and see if it stops doing it when it shifts on the earlier map

ill start up a thread the sarvo mate, i dont think it the limter because its still dead when its in second for a bit any way its going back into the shop next week they can find the gremlin..Dose anyone know where i can get a vs hsv caprice back rear skirt im taking off my toe bar and ive got a big hole and its also got a big crack in it to im thinking of just getting a new or replacment i reckon it will be heaps cheaper doing it that way...maybe someone who dose fiberglass kits??

they do that a bit we had the same issue with the vs turbo as soon as it hit the limiter it took it a second or 2 in 2nd gear to start pulling again dont trust the dash tacho they can be way out and dont move fast enough if you have good acceleration speed youll hit the limiter before they say the correct rpm a lot of times

I just took it for another strap and it isnt as bad as the other day but it is still noticable,its only doinig it when you have the power botton on umm might just need to stick some skinnys on the back and fry some tyres,that might clean it out lol

Might try changing the filter too - never overlook the simple things
