Undercover performance? Nj ?
Looking to get a pro efi sytem and i found a shop called Undercover performance in nj.
Apparently they install and tune rotaries. And are having good results.
I have never heard of them before...
have you?
any thoughts?

im currently with jim now and he is awesome. aside from him being the only one there so getting cars out takes a while but hes is good. Just looking for an ecu like the pro efi to do on the fly map switching with e85 and pump gas. thats all.
Best bet is to ask jim.
Because he can refer you to people that HE knows.
Asking people here and even if someone pm's you, are you really going to trust their work? If you dont know their tuning history?
I mean a tune is a big deal. That can make or break your car. So to speak.

Never heard of them, only person ive EVER heard sucessfull with the pro EFI is RAY @PFS,
Ask jim to give ray a call, he can get you some details...
As far as time and money, hope you got alot on tap, 3k for just the ecu, then price in wiring it ALL up (2-3k) then Tune for how many fuels ($,$$$)???? gonna be 6k EASY!
