Ott > Gm

 

The ott kit is a kit... it come with everything you need.. in cluding tune..

the ott kit will produce more power... and allow to make more power if you wish (since it comes with bigger injectors)

The GM kit, if installed by dealer, will keep your warrenty.

OTT kit is better in my book.

 

thanks ok. well gm might go bankrupt on june 1st now tho if you havnt heard so idk what to do..

 

GM (the government, actually) will still be recognizing any warrentys left on the car.

 

Get the OTT I haven't heard anyone with issues and the customer service seems to be really good. Also the price tag is alot more appealing as is the power.

 

OTT kit is better overall, and gives you the right parts to go for even more power down the line. With GM S2 you are pretty much maxed out already.
