How much does it cost at a shop to tune the computer chip on a L98 350 tpi?
Also i have headers and im runing just a y pipe with no muffler coming out the
side, does the 350 tpi perform better with no muffler?

call your local tuning shop and ask...

for eric brooks to do my cobra was 400 then 50 for the dyno rental

Do you think that im incapable of calling them? Or that i was incapable of calling them until your superior wisdom enlightened me to grab the phone? Everythings closed atm numskull, so I, being the curious individual that i am, journeyed through googles jungle and ended up in this land of primitive beings to be bestowed adorable answers that never make real sense, but nevertheless i enjoy the thousands of people and your 3 delightful woman, so keep providing me with puzzling answers that make me smirk, its what gets me up in the morning and its what puts me to sleep, i love you stay strong
You beautiful angel ill always be with you.

haha.

so you couldn't wait to call and ask? Also if you used google and didn't get an answer or a general idea of a price than maybe you should just quit the internet.

I got my WRX dyno tuned for 250

Holy run on sentence...

Id imagine it would be somewhere around $200-400

?




and this sounds about right to me, all shop dependent.

Thats pretty standard.
