Screw the warranty. It’s not worth it for the canned tune that is terrible. I’m in CA and have an Edelbrock Stage 2 with Lund tune. To pass smog, all I have to do is reload the Edelbrock tune. Roush and Whipple canned tunes are slightly better, but still not worth it in my opinion.
Custom tune is absolutely worth it. You can always turn down the boost with a larger blower pulley and run some octane booster for safety. It will likely still make more power, have much better throttle response, and be safer.
I have the Edelbrock Stage 2 and if the warranty is important to you, the Roush Phase 2 may be the better option. I'm sure the Roush canned tune isn't great, but I can tell you from experience that the Edelbrock canned tune required to keep the warranty is complete trash.
I try to stay out of jail these days, but I'm glad that I installed them!
They just take some maneuvering to get them to line up. Also, I had to pull the bumper in while pushing outward with the belly pan to get all 19 bolts to line up underneath.
