R-Tech stage 1 last week
Vandyer:
Hello
After much research I took my car to R-Tech last week for a stage 1 remap.
The guys down there know their stuff and Niki identified that my car was suffering with a problem with flow..... Post remap 287bhp which I'm over the moon with but he reckons that was lower than he was expecting ....
Anyway, time for a schoolboy confession - I filled my car with diesel and drove 4 miles.....(it went to VW main dealer for fuel line drain, new filters etc)
Question- do you think the cat or pre cat might be blocked with diesel particles??
Niki was kind enough to give me a exhaust (the middle bit) and it's had the pre cat removed- he suggested fitting it and see if it helps
I'm delighted with 287bhp but can't help wonder what damage my schoolboy error has caused.
Any advice welcome
alexharvey:
get the downpipe niki gave you on the car!!
cat might be ruined on yours
GrayMK5GTI:
I saw this on Niki's Facebook too!
Blocked cat sounds plausible so get the FREE downpipe fitted and see if it's quicker :happy2:
May be worth checking your air filter as if it hasn't been changed recently it will hold back the power a little bit. Maybe treat your car to an updated Pipercross Panel filter (£35 on eBay)
Vandyer:
I sure will get the exhaust fitted...is this a simple DIY job or more specialist?
As for air filter, was planning that too, especially the relatively low cost
GrayMK5GTI:
Exhaust is only 4 bolts and a clamp. Any decent reputable garage can swap it over, ask them to remove the pre-cat from the exhaust Niki gave you as that will free up at least another 5bhp
