LSX 90/90 on larger ci
I just cant decide if it is worth the money, but I feel like my motor needs it, this may seem obvious but...
Is the LSX 90/90 TB worth the money? What gainswould I expect?
Is $1200 worth it?
I think the major ? for me is, do I want to try to max the motor NA or just take the easy way out and put a 150-200 shot on it...
the ls6 and stock tb are restricting the 408, open her up and you will see a big difference is idle, stability, power and petal feel.
See the dyno results, you might be surprised. If anything i would suggest another TB since the fast 90mm have some quality issues that are, IMO, not worth the $$.
this is wat i would suggest:

find the Nick WIlliams TB, its a 90mm and i've only heard good things about it.
good luck!!!
