well do u have a v1 or v2? The V2s are a lot quieter than the V1s. And I just started it with the new tune for stock maf and injectors, and the motor definately wasnt shaking like it was before..Do blowers make your rpms drop faster? Mine definately drop a hell of a lot faster than they did before. Also, dont exhaust shops have something they can put in your exhaust to check for leaks..and how much does it cost?

Just jack the car up and run your hand over all the connections.. you will feel an exhaust leak

I have ran 42's and 60's on same maf it's calibrated in the tune.

I run 60's. I know tons of people on other sites running 500+ on a s-trim. The only reason I didn't break 600 was I was running out of fuel. So we didn't add anymore timing. But after 550 I think it's better use a T-trim. But **** I already have this and I'm poor.

So you are saying hes wrong and that I do need to put the bigger maf and injectors in the tune?

Trust what ox is saying about the sniper. It makes since to.. if the maf is calibrated it is already set up IN THE MAF for those injectors.. so adding it in the tune is throwing it WAY off.

i know it makes sense. the maf is calibrated for my 60s, so as air goes through the maf tells my ecu that i have 60 lb injectors and gives it fuel accordingly

Using this example, ANYTHING besides 30LB. injectors you say exactly what you have?

exactly thats exactly why you needed to put the stock settings back in the sniper tune
