I just purchased a 2000 camaro z28 with a 5.3 turbo charged. The car was tuned running e85. I need it retuned for 91. I do not know where a good tuner is around where I live.

I called a shop in Nebraska today. The guy told me id have to swap my 80 lb injectors to 60 lb. Also said I'd only be able to do 10 lbs of boost and be around 450hp.

Seems low to me.

Help please!

We can remote tune it if you have efi live or hp tuners. We usually remote tune 1-2 boosted cars a week at a minimum. Just finished tuning a turbo 5.3 mustang running 18 lbs of boost on 93 oct through email.

I don't have hp tuners anymore. I could get it again.

So I'd log the car and email the file to you, you'd adjust it then send it back. And keep doing that till its dialed in?

This is what happens when it hits boost.

Yes, thats exactly it. It may take 3 emails, it could take 15 emails. Theres no limit, how ever many it takes to get it dialed in right.

Thats a pretty typical setup, nothing crazy or out in left field that should be a problem for tuning. I would also try using your 80's first before buying new injectors. Depending on which ones you have they will most likely work.

We sell EFI Live and HP Tuners also.

By watching the video, what do you think is going on?

I watched it several times and honestly cant tell. Have you checked your plugs, fuel pressure, etc?

I haven't yet. I need a fuel pressure gauge. Haven't pulled plugs yet because I want to put new ones in but don't know what ones I need.
