Great customer service!:scream:

I ordered this kit for performance & reliability & zzp has proven time after time to deliver. This is a must have if upping boost.I installed this kit & managed to break a pin on one of the connectors. My fault & zzp fixed it by sending me a new one. I'm very impressed with Ryan's customer service. They really didn't have to do that but chose to fix my problem. They stand by there products & respond quickly via email. I'm just an LNF owner that wants reliability & performance & zzp doesn't know how to do it any other way. Oh & get the lower charge pipe. It's mandatory to change the stock tmap location seeming how it rubs on a/c line . zzp lower charge pipe is the fix!

Really wakes it up

Can't beat the price on these especailly when you include the ZZP LNF PCM tuned for them. Definitely gives the car its much needed pep. Turbo spools up MUCH faster, pulls hard. Hits 27lbs of boost on stock turbo at WOT. Lower sensor is the most difficult to get to given the proximity to try and get the screws out. I ended up ordering the ZZP upper/lower intercooler pipes and installing it altogether.
