Would have been great to seea pro tune with OEm cats and then the high flow cats.

Solid gains and am sure it is a rocket.

Have access to a Dragy or any 1/4 mile runs?

The 2M cats......I have been seeing some shaky reviews...I think I am just leaving my "cats" stock for a while.

Definitely don't buy those myself and others have check engine light issues with them and 2M is not helpful

Personaly i have dynoed 510whp with APR GTS STAGE3 and did 10.7@131mhp and 6.7 100-200
Was that on the APR 91 octane Stage 3 without the intercoolers? Their site claims 520 hp/524 tq and I’ve always wondered if someone has independently confirmed it.

APR STAGE3 93OCT 510whp with Tial i/c ,intake piping,headers ,test pipe... to compare stock gts 450hp trap 124mph vs apr 131mph so that is about 70whp gain from stock gts that would put me around 540 crank hp

I went back on their site and looked at the crank figures for your setup and it claims 582 at the crank. Could this be attributed to a difference in the type of dyno used?

I ask because I have their 93 Oct Stage 1 tune and it says I should be making 475 hp/461 tq but it’s not that high in reality. Still happy with the tune. Feels like a totally different car now.

Try the 1/4 mile ..that will tell you the real hp your making with the trap speed

Heres a good tool to calculate crank hp

https://www.google.com/url?q=https:/...Bq0ssbLUdgE0ta

using this tool car weight and trap speed 3454lb+me240lb+75lb fuel=+-2769lb trap speed 131=661hp that seem very high using this tool

That’s fast!!! Ive seen these calculators before. I think @AlexZTuned used it to estimate his setup which came out to 650 Hp so maybe it’s accurate since you two have similar mods.

I’m getting the headers, Tial intake, diverter valves and BMC filter installed today so once it’s back I’ll borrow a dragy and see what she puts down
