tried to do a search under "90mm gains" didnt find much, also just tried "90mm", but anyone who has it listd under their sig shows up, so no go on that search. Does anyone have documented gains from swapping from a 99-00 to the new 90mm?? I already have filter, but I think I would need to buy a new one(??). Total cost will run about $350 for both. I want to know what kind of gains I will see from this, need to justify the cost. thx for the help Yoda

 

The tuner's have got the 80's so refined that by adding a 90mm with a good program you won't see that much if you already have a good program for a stock 80. I would guess maybe 5 to 10 hp.

 

switch at track dont know if it was the program or meter or both but i gained 2 tenth's
