If he had any real sence hed turn the boost to stock untill he had a wideband. a wideband is the most important thing when tunning its like puting in a walbro 255 with no fpr. this a good example why dsms get a bad name. its because people just turn up the boost break it and wonder why and if your running stock injectors why the hell would you run 16lbs on a bigger turbo again you know you dont have enough fuel for it. When i put a 16g on my car with stock injectors i ran 8lbs of boost. when i put the safc2 and maft in back then i ran 8 lbs of boost. When i put a wideband in 2 weeks later. boost went up to 25lbs. If you did some reading like you should have you would know on a stock turbo 14lbs is the max on a stock fuel setup. maybe 15-16 tops with a pump. you say you'll break the motor and get a new one go for it but you'll be bitching about it

Call it what you may. All of your assumptions talon187 are incorrect could i buy another of course. You read the log and look at the boost est and its way wrong. If you read my profile You'd see what turbo it is and what modifications i had. You talk about getting a bad name. Ask questions and You'll get answers your assuming i'm doing things that aren't true. And for the record i fixed my problem. Deadtime was wrong. So talon187 pissoff. To all with positive info Thanks too you others, no words.

K so you've got 750cc injectors on a 19C.

What are your plugs gapped at? I'm assuming you've done a boost leak check?

Definitely buy a wideband.

Buy a wideband and get another tune and see if that helps the problem

plugs are at 28. no leaks anywhere. i ordered a wideband from extremepsi. now just a matter of getting it installing and having it tuned professionally as talon187 suggested..

apparently my deadtime was at zero, so i looked through dsmlink website and found the suggested deadtime and stared there.
