I have an 08 GT convertable, Roush supercharger and off road exhaust. I am wondering, is there a way to get about 50 more hp out of the engine, without a computer retune and without obviously voiding warranty? I have read alot of threads here, but still am not sure there is much I can do. Pulley would void everything I assume.

 

I going to say No way

 

No. If you want to play, you have to pay the price. That said, you can put on a CAI and tune and just put everything back to staock anytime you take it to the dealer and hope they don't say anything.

 

Talk to the guys at Fnsweet.com (Roush Forum) I thought they were all doing pully swaps under warranty???

 

There's something funny about warranty. The warranty is not voided as long as the part you put in is not the cause for the fault. 4.10s don't void your warranty, but if installing the 4.10s caused the rear end to get ruined, then it will void the warranty. This is coming from the dealer and a Powered by Ford shop here in the Orlando area.

 

A dealership will have a hard time voiding your warranty unless they can point to the part in question as the part that caused the failure.
