I have my car booked in next week for a full de-cat system. I am reading alot of threads about the trouble de-catting a sti v5/p1 cause. Are these problems rare or do the actually happen alot. I have ordered a knock link and a boost gauge going by John Banks advice thanks John. I have also been told to get another fuel pump by other guys? How much are these? Do i need to get it re-mapped? Or are alot of you guys out there running your p1/sti v5 de-catted without re-map and causeing no trouble? This is just to put my mind at ease. Thanks you for any info Gary....

STi5 with ITG p/f, Scorpion d/p & c/c, Scoobysport b/b. Running on Optimax & Millars octane booster.

With this set up my car would det at peak torque in 3rd, 4th and 5th. This was checked via det cans (Knock Link was 80-90% accurate). You could not hear det in the car.

This was a couple of years ago now but IIRC peak boost was 1.35bar.

I stopped the det by drilling the restrictor out by 0.1mm.

An appropriate remap (along with a few choice mods) would be the best solution. Could save you a small fortune in the future.

yes you should get it remapped. Octane booster will help, as will teh detection gauges, but to be sure get it remapped

Thanks for the info lads. So its a re-map then. What would i expect to pay for a re-map?
