so i got a engine swap about couple months ago went from v6 to v8 i got a tune from a friend who works at a shop. tune felt alright couldnt really tell a difference coming from a v6 to a v8.

so i got a dyno and it was reading very poorly. hp peak was at 5300 which should be 5900. seems lik the 600rpm just took a vacation. is this a tune problem or engine problem???

sorri no A/F they dyno didnt hav an A/F that day. also i look at my a/f on my diablosport and it was reading rich 14s at idle.

im also thinking about getting a new tune from Bama Tunes do u think its a better idea to get it from them?



thanks

 

Most any EFI vehicle will idle at about 14.7:1, thats stoich, and not rich by any means

Im not sure there is any problem here...does the car has a CAI on it?

 

yes it does hav a CAI made by steeda and also got Charge motion delete plates too

 

What was your a/f at WOT?

 

Assuming you later got it checked.
