Which (If any) Chip would you run? S4S

Recommended Posts

Hello

S4S - has 3 inch cat-less exhaust, alunox manifold, BOV, larger 2ndry injectors (RC)....

I was going to run Chip 3 - high torque as I won't track it much....

Is there a better chip for my set up? Or should I play it safe and stick with the stock map?

Thanks for any input!

I ran that chip in my S4s & she would spin the wheels in third on a good dry road when the turbo started boosting, great fun but had to be bery careful in the wet. 😃

I have a chip No.3 fitted. My main reason for fitting it was to smooth out the GM stumble that I had with the standard S4s chip. It makes things slightly more lively, but not ridiculously so, and I have to say that I’m very pleased with it. I didn’t go any further up the numerical chip tree, because the GM MAP sensor cannot read beyond 1 bar of turbo boost, and I didn’t want to risk damage to my engine. I think that if you get beyond that boost figure, you’re into the unknown, and a stand-alone ECU is arguably the next step. Any more torque, and it’s time to look at the gearbox, too.
