NickFullman Posted October 28, 2014 Share Posted October 28, 2014 If I remove the 1st cat do I need to remap? Just bought the car and prior to buying it was running at 0.5 bar boost, the issue was the 1st cat was blocked, I was told it was sorted how do I know??? If it hasn't would I be best off replacing the downpipe from the turbo with a cat free pipe?? Hence the first question Nick Quote Link to comment Share on other sites More sharing options...
KG Tuning Posted October 28, 2014 Share Posted October 28, 2014 0.5 BAR will feel sluggish. Put a sports cat downpipe on it, that way you'll know if you make target boost as it'll feel rapid and it'll run a bit safer until you get a remap. A quick test to see if you can make boost is to pull the vac hose off the actuator nipple when the car is warmed up during the hottest part of the day and floor it in 2nd gear. The car should make around 1.4 bar. Don't floor it in 3rd gear upwards as you'll most probably get a violent fuel cut. If the car feels much faster then you know you don't have a bad boost leak, "blocked cat" or stuck open wastegate etc. 1 Quote Link to comment Share on other sites More sharing options...
NickFullman Posted October 29, 2014 Share Posted October 29, 2014 Its not sluggish at all... I don't have a boost gauge so not sure how I will know what bar it is running at. If I do go the whole hog and decat the turbo downpipe do I need a remap? Quote Link to comment Share on other sites More sharing options...
KG Tuning Posted October 29, 2014 Share Posted October 29, 2014 Yes, asap. You can run without remap for a time if you stay off boost. Decatting without a remap won't give much power just a quicker spool time, boost spikes with the chance of detonation and a CEL. If you remap after decat the car will generate up to 20bhp, run far safer and probably more economically. Quote Link to comment Share on other sites More sharing options...
