Tell them to lean it out and make a little more power.

SMG Motoring in Hopedale, Ma Has done Cobalt builds from stock with bolt-ons and dyno tunes to full custom turbo setups near 400whp, twin charge remote mount builds, nirtous setups, as well as full GM race block custom motor builds.

If your serious about making 300whp talk to Fred @ SMG and he will let you know what it's going to take to do it the right way. From supporting mods to the type of power adder to you need.

5082444225 ask for Fred tell him JC told you to call and you will get real advice.

port and polish the blower, add meth and a 2.6 and opion b or dual pass and u will be real close to ur goal with the rite tune

which one you recommend?

AEM wide band is great for the money. Keep in mind that most people on this sight giving you advice never made 300 whp. And, probably never will even on the happiest of dynos.

thanks. I also have a question on the ZZP boost reference fuel pressure system. Is that necessary to instal lif your running 60# injectors, if so would i be seeing an increase on anything?

Instead of buying a TVS, buy OTT's stage 3 kit. It'll come with everything you need including the tvs for a couple hundred more than the TVS itself costs

so i added the stage 3 H/E and 2 step cold spark plugs now i have to retune the car, which one is better trifecta or hptuners?

You really should get meth or convert to e85 if its available to you to make what your looking to get. And hptuners would be better because you will always have the tuning software. Just have to learn what your doing first.
