i was wondering if the hv intake insert is worth it. Will i really see the gains they say ill see?

From heresay, it gives you more upper RPM power. It should give you a nice gain up top.

I noticed a gain when i added mine on a pretty much stock engine. But without supporting mods it has the potential to really take away from your low end.
So, if you don't plan on either getting a cam or rockers and revving up to 6300 or so(which is impossible without a pcm), it'* not worth it.
It'* really still up in the air as to if its really benificial.
I'd send the money on some ported exhaust manifolds instead.

Theres no 'chip' in a 96 it'* OBDII
And i'm not so sure about those wp pullies because Allmachtige had to file down his p/* drives mount to make it fit.

I just re-read and it said your not really on a budget.
You should get a GT1 cam, LS6 valve springs, Oil restricted pushrods, a L67 TB, PEMS, a mini afc to tune a/f ratio, and hold on!!!!

I know with Insert, PEMS, reworked rockers, and a ported TB it makes some good high RPM Power but low RPM power did suffer - Or is it justs because it pulls soo much harder at high RPM?

If your not really on a budget and you want to make some HP then turbo is the way to go.
