So I had my car tuned by trifecta, and I've done data logging and all of that and had it retuned twice now but still no fix. My problem is when I have the tune on and I floor it and no lift shift from second to third my car will bog out and starts to misfire rapidly and I cant get the car to pick up speed again till I slow down...anyone ever encounter anything like this?

 

you probably hit the HOLY **** threshold and your car wont pass it lol

 

How many miles?

 

Almost 30k

 

No body? Damn

 

no codes, my car feels like that right now because im throwing a lean code. not saying thats what it is, but fuel pump or MAF?

 

you might need new plugs cause when i nls from 2nd to 3rd my car will bog and throw a misfire in cylinders whatever its in i bought some new ngk plugs see how they work but when you nls does it sound like the exhaust is popping then you take your foot off the gas slow down then get back on it and its fine?

 

I throw a lean code every once and a while its on and off and yea that's exactly how it feels..let my foot off for it to stop firing and then I can go back to punching it
