we just purchased a stage 2 kit and was wondering if it was safe to run the rr racing computer with it we heard that it made the fuel to lean and you have to install new fuel injectors and a piggy back to make to the right mixture. does this sound right and do you have pro series block off in stock and can we swap out the block off that come with the kit and get the pro series instead? our dealer is checking but i would like to no if we can from you guys. cant wait till it comes in

Are you asking me (RIVA) directly?

yea u riva

Ah...

Can't comment on what will happen if you use the RR ECU with out Stage II Kit. It's not required. The stock ECU works fine!

Yes, the Pro-Series Block-off Kits are in stock. (Posted that a info a few days ago! ) Please work with your dealer if you wish to swap out parts they already ordered for you.

thanks we did work with our dealer and got the pro block offs have u guys ever put a rr computer on a stage 2 rpx? just wondering what would happen

We have not tested RR's ECU with our Stage II Kit.
