I bought a Pro Systems carb back in 2009 for my 512 big block. It did very well for me at the track, but I have since retuned the engine (lower compression) for the street and talked to Patrick about sending it back to make it more streetable. I asked what the turn around time would be and he told me it would be a week. After two weeks I hadn't heard back so I contacted them and was told that my carb "was next in line" how many times have we heard that from customer service reps after they forget about , or put off our stuff?? So she said it would be done the next day, Wednesday. I told her I would pay extra for 2nd day air so I would be sure to have it on Friday. Friday came and went and nothing. I left a message on their phone, never heard back. Called back this morning and left another message, no returned call so I started calling every half hour or so. The answering machine picked up every time. Right after placing a call with my own phone, I tried my wife's phone and low and behold, they answered immediately.

I explained the situation, and she acted like she totally forgot the conversation we had on Wednesday, so she started looking things up. Turned out that it didn't ship until Friday afternoon. The person who shipped it shipped it UPS next day. She said it was supposed to be here on Saturday, which would have still been too late, but the UPS tracking showed it was always supposed to show up today, Monday.

Just want to pass this on because customer service makes the world go 'round. No one likes to be misled or lied to. There are plenty of other options out there for high performance carb work. I know where I won't be sending mine in the future.

Years ago Patrick was the only guy you would talk to. Bought several carbs, zero issues.
These days, doesnt seem you get the personal touch, either on the phone or in quality.
My soon to be next carb wont be from him

It's been years since I've dealt with or even spoken to Patrick. Sad to see their customer service has gone downhill b/c they used to be great.
I have 2 carbs he's done for me and I've been very happy w/ them.

Get in touch with Dom@Thumpercarbs. He will make your carb better with better service as well. Many happy customers over there.

Another vote for Thumper carbs.........

My Prosystems carb tune was out to lunch....even though I filled out one of there sheets and gave them all the info.....Tune was real bad. I spoke to him couple times, seemed like a smart guy, too smart for a simpleton like me to understand. I gave up on dealing with him. We had real good luck with Proform race carbs, so I looked up their jetting, basically the same size....Put all that in my carb...ran like a scolded monkey after that.....Tuned it in and ran for many years. Lent it to a buddy of mine that was having trouble with a brand new Quick Fuel carb, and he picked up over 1/10th.....He wouldn't give it back, so I sold it to him, and this began my relationship with Thumper carbs.....

I say relationship because we still talk ever other week or two about the tune in one of his carbs I have. With his, I picked up even more ET and more MPH.....and he helps get the tune where you need it...THAT's Service! Although I think Mopar Dave there is out spending me by a bunch this year...I have been real happy with mine.

I appreciate you guys that have given me a chance to TRY and make ya happier and faster and sometimes we knock it outta the park and other times we need a bit more tweeking but they ALWAYS come around in the end and also thanks to you guys, I've built, modded and sold several hundred as of now........Peace
