manifold and de-cat?

[Dan Evans]

I've just bought a SPS De-cat and soon to be buying a SPS race coated manifold, just wondering once i have fitted these, will i be needing to get my ecu remapped?? it says on TOYTUNING they recommend getting a remap when fitting a decat... This true??

Also is an SPS manifold a good choice?? or what else would be good for similar money??

I think its because you may experince boost creep...good site http://www.turbobygarrett.com/turbobygarre...enter/faqs.html

I've got a JAM racing FCC so i wont get boost creep, will i??

They are used for fuel cut, over 0.80-0.85 is when you get fuel cut.....When doing such mods i.e decat,mani,exhaust,air filter boost will creep over the set ammount and some times over 0.85 thats when the EM light will come on and it will feel as if you hit a wall or something?. the way to eliminate creep is to port the wastegate to a certain ammount.......my turbo knowledge is weak mabe some1 could help scooby out a little more?
