i have an eb xr6 wagon and wanting 2 put a new comp in. It has 140kw at the rear im thinkin with a new comp and bigger injectors i could be pushin 180kw. Just wanting 2 know what type of comp would be recomended i was thinkin of a micro tech LT10 orLT12. any suggestions?

you are not going to get that much power just from a computer and tune.
you might pick 5 or 6kw and at that sort of power ou dont need bigger injectors.

if you want a microtech call them and they'll point you in the right direction

Find out if the stock injectors are running out of squirt before you go spending money on bigger ones.

What sort of AFR's do you get at the moment? This will indicate how much power you will gain from a tune.
