i have a turbo back exhaust 3" catless, and a HKS RS intake..... what kind of power gains shoudl i be expecting... i was solely just leaning towards vishnu but i wanna see what other places offer. and how much.

oh and finally with a reflash does this fix the p03000 reflash, also does your reflash disable the cel that is thrown by running catless???

 

Here is a fully custom tuned version of my flash - similar mods as yours but this gentleman had the same mods you list with a MBC and a walbro fuel pump




That flash is $199 in a base version via fed ex

OR - $399 as a fully custom tuned version in your town

 

I have Buschur Stg. 5 and dynoflashed and I couldnt be Happier..
