My Experience With GPI

[hammdo]

In one word -- AWESOME!

Aaron, James, Ryan, Mike, and the whole crew are truly experts.

My 2011 2SS L99 A6 was the car modded.

I had already added the Vararam Intake (No Tune Version), Vararm PowerWedge, VMax TB, and JBA Wires.

When I arrived, I met with James and Ryan to go over what I wanted done and approximate time-frame to get it completed.

The first item on the list was Ryan doing the initial Dyno.

With the mods I installed, the L99 did consistent 365 RWHP. I did not have a dyno of it before the mods, but based on Ryan's experience, I gained about 25 RWHP with those mods.

So, the team at GPI did the intake mod, Installed the Stainless Work LT 1 7/8 header with the High Flow Cat and muffler delete. These parts I purchased from Maryland Speed (GREAT customer service!).

Then came the under-drive pulley and 3.91 gears.

Once those were done -- back to the dyno and ...

402 RWHP and 402 ft-lbs Torque!

This JUST from bolt-ons. One run was 404.9 -- but the consistent run was 401.8 RWHP

So, the initial drive after completed, Ryan and I drove it near a 'straight-away' to see how she does -- 3.91 with that power REALLY snapped the Camaro into shape!

So, these guys know their stuff -- they are gear-heads

So, why did I drive 5 hours to them?

When Ryan and I spoke, I knew he had a total understanding of the car and its capabilities.

I did check around the 'local' shops. Some didn't call me or email me back -- others were quick to respond.

The one I thought I'd go with wanted 50% up front just to get on their calendar and it was a month wait.

I ran an automotive service center for 7 years and that just rubbed me the wrong way. Maybe I'm picky about things like that...


Anyway, GPI and the team were just on it. They knew I was driving 5 hours and the total deal with a Rental Car, was just awesome.

To the entire GPI team. BTW, GPI is a Chevy Dealer -- imagine that! Not like any here in Dallas I've seen or talked to personally. The one's I did talk to look @ you cross-eyed when you want to do 'performance' upgrades.

I will most certainly contact GPI again. If you want to do the bolt ons and get the most HP, I can attest to their magic.

BUT that is not all they do...

I did see them working on an SC Camaro -- this one is over 800RWHP (I believe he is a member of this forum too!)


Yes, Yes, Yes, the proof...

I do have the dyno slips and pics (not the gears though) and will post them after I've had a chance to 'rest' from the trip.

Just awesome -- my Jack Nicholson smile (think Riddler) just won't go away after doing that for 5 hours -- the wife (who went with me) enjoyed the drive and the new 'Camaro' -- caught her a bit by surprise with the before and after

GPI is just awesome and worth the trip no doubt...

I've been working with Ryan (Rhino) for the last 9 months on my tune and other tweaks and what have you, I have nothing but good things to say about the guy. I'll echo your sentiments, for what it's worth.

[hammdo]

Ryan did say, I should see 11's with this puppy -- not with 'stock' tires though ;o)...

I'm willing to go to the folks who take care of me and who know their stuff, but don't 'act' like they 'know' their stuff -- if you get my meaning...

I really liked GPI's 'family' attitude towards me. It was fun just to 'chat'. It reminded me of the 'old school' performance shops I grew up with -- but with the 'modern' twist. That is hard to come by and GPI does that well.

They typically have LOTS of cool old muscle cars to look at too, which is weird for a dealership. Frods, Dodges, and Chevy's.

[hammdo]

Axis -- what were your dyno #'s?

AND

do you have a pic of that 'train' you parked ;o)

[Chevrolade]

Good to hear

[hammdo]

Damn, my face is sore -- can't stop 'smilin' even after 5 hour trip -- GPI does that to you:

[Rhino79]

I appreciate the kind words Don.

We like what we do, and really enjoy helping you guys out. We do a lot of stuff from surrounding states, and we try to accommodate you guys when you make to road trip to us. We know you could go anywhere you want. We aren't always the cheapest, but we proudly stand behind our work and take pride in what we do.

I hope you enjoyed the ride home V4 mode free....lol.

[hammdo]

Damn fun -- tired and I still want to drive it -- wow does it perform! I had to 'pass' a few cars just to 'make sure' it was not a dream

[hammdo]

I'll say its kinda 'funny' how folks move out of the way when they 'hear' it kick in

Here's my thread. This was before gears and Bo's TB.
