V1 Won't take my money.

Well, I've been told no. I called the shop that dynotuned my car last spring and asked them to possibly modify my engine with a new cam, etc. They won't do it unless I install a larger turbo. I have a z54 (on a 2.0 lnf) right now with about 1,000 miles on it. I'm not interested in replacing it yet. I don't want the longer spool time either. Basically told me the engines aren't that great for building power. I want a modest 350-400whp. Ideally, I'd use their dyno that registered 240hp.

What are your thoughts?

Look for another shop. Anyone who is saying the Ecotec is not 'that great for building power' is not a fan - probably only wants to work on Hondas - and doesn't have a clue.

The z54 is big enough for ~500hp, you definitely don't need a bigger one. I don't think you need cams either for your power goals. I'd find a new shop, or have ZZP do a remote tune.

I was floored.

The current turbo with E85 and a tune could probably exceed your goals. I'd put the money for cams towards that.

Agree 100%. I'm considering road tripping up to ZZP for a duno tune after I get my 5th injector installed, will keep you posted.

ZZP says...
"With a full list of ZZP parts on our ’08 Cobalt SS, we achieved 480 wheel horsepower on E85 (Z54 turbo)"

Guys, E85 is not always readily available in all parts of the country. There are only a select few stations around my area where E85 is available here in south eastern PA. 93 is plentiful though.

I do agree though, if they wont take your money, find a place that will and that understands your build better.

E85 is pretty much everywhere around here, smack dab in the middle of corn country. I will always have a 93 tune on the laptop in case of emergency though lol

E85 availability is why I am on 91 octane with methanol injection to keep the IAT down. Every year I am making more adjustments to get "more power" so I will eventually get there and just have to store E85 at home for everyday use.
