Just finished installing the TVS1900, followed the directions exactly. Engine will usually start and idle just fine, sometimes it has a bit of an issue...I figured it was leftover air in the fuel rails. I can accelerate, but under WOT it pops the code and the engine reports "engine power is reduced". Code that pops up is P0068, MAP/MAF - Throttle Position Correlation. Anyone seen this before? It's barely drivable with this.

 

Need to have that adjusted in the tune. Have you have it tuned yet???

 

sounds like you need a upgraded maf? same thing my truck did with the stock maf after i installed my turbocharger.. i was pegging the maf and soon as it hit 400gms of air per second it would kill the engine and it would die/sputter

a upgraded maf should be able to read up to 750-800 gms of air a second but will definatly have to be tuned for..

 

no need for upgrade MAF, adjust the tune

 

I figured it out. The tune is set for a 1bar map, while I had a 2bar installed. Swapped back to the old one for the time being.

 

How's it running now

 

it screams

 

I'd love to see some numbers haha

 

nice...that 60e isnt going to like you very much...

 

Which map sensor did you end up using? The one they suggest?
