Hi VR_V6_MANUAL,

"Hi mace im wondering what gains should i expect on a ecotec.. i want to buy the high ratio rockers and the 12mm spacers and bigger throttle body"
With the 1.9 high ratio rockers and both 12mm spacers (manifold and plenum) I would expect to see approx 16-20kw increase in power. The throttle body will give a slight increase in power but mainly help improve throttle response.

" at the same time iv already got CAI and 2.5inch cat back exhaust and i want to get it tuned after all that. is there any other mods you would recomend for me im kinda restricted as im on my ps.. dont realy have a budget tho."
Your existing mods will complement those you are looking to add. I would recommend adding a 82 degree thermostat. We can supply a tune to suit all those mods.

Please don't hesitate to ask if you have any more questions.
