THis is pretty simple..I have a 2nd gen teg ls turbo pretty standard t3/t4 setup..I have 450cc injectors and was tuning with chrome..I got a Map from Xecron that was supposed to be good..BUT..this is my problem..IF i drive the car normal(meaning NOt allowing the car to enter boost, it Drives perfect..), but as soon as i try to step on the pedal and enter boost..it's just breaks up and doesn't let boost..i personally think..i need to get it tuned. BUT one of my good friends is set on it being something mechanical..i've looked over the setup with 3 or more different people and everyone says the setup looks fine..I mean theres not that much to a turbo kit.. FOOTNOTE: ive went through about 4 pairs of spark plugs moving the car a few times b/c their dripping black when i pull them out after starting the car..ANY ADVICE ?? or should i go with my gut and spend the money to get it street tuned ?

 

you should really get it tuned..

 

what do you gap your plugs to? should be 0.022 - 0.028 for boost applications, maybe that is your problem?

 

a tune on crome should be fine if your mechanic knows what he is doing. you did a "live tune" right?
