Recently I swapped my blown sc-61 turbo for a new sc-61. Prior to the swap my car was tuned to 450 at 22psi. Now after swapping the turbo I am running into a few problems. I did the swap about a month ago and did not have much time to drive the car. Yesterday I went out and ran into some problems. When I was in WOT at around 10psi the car would start to pop and bog down. Won’t go past 10psi. At minimal levels of boost the car drives fine. Tonight I’m going to look for vac leaks and do a compression check. If the compression check turns out fine, what else should I be looking for? The car did not over boost prior to this problem. Could this be a problem with my tune? Any suggestions??

Thanks!

 

I was having a problem where my spark was being blown out cuz of crappy spark plugs and the same thing was happening. Check ur plugs.

 

Have a Wideband in the car ?

 

It might that you are lean on fuel...
Try turning up the fuel pressure a bit.... and see if it still does it....

 

Plugs, Good point. Did not think about that one, Will change them out tonight!

No I do not unfortunatly

I have a fuel pressure gauge and its constantly showing around 42psi. What should I up the fuel pressure too?

 

"tunes" dont usually just "go bad"

take a look at your plugs

 

thanks guys, problem solved! It was a bad spark plug wire, the one running to the ignition coil. swappd it out and everything is good!!

 

nice
