with the above mods it has been done before 4 sure and you will have mixed answers on that question...the better question would be can i go with a 3.5 with the above mods without a tune(stock pcm) with at least a scan gauge...yes you can then check for kr and see where you are at!

when i say a tune in this case i am refering to a reprogramed pcm


And if you get the hp tuners i can give you a tune that is on my stock gtp(parts on order) that is very very close to the dhp 1.0 tune...
