wanting to tune my 02 1.8T, do I do AWE which is GIAUSA chips, or go APR. I have a intake, exhaust, diverter valve. I have a check engine light says catalyst below efficency, I have a test pipe just havent put on yet. Problem is AWE says cant remove check light. APR says their program can, remove and to put test pipe in. I can do standard stage one type and I am maxed out. APR says need to replace injectors, the tuners that sell APR here say they want me to by there injectors at 440 plus tax. I met a guy with a AWE tune and he put injectors in his car, he was told to the 225 hrspwr Audi TT injectors in, they costed about 225 plus tax. Where do I go, any help would be appriciated. Oh by the my car is a 5 speed Quattro.

 

Please anyone on thoughts
